Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chips, and in particular to a hardware link aggregation deployment method and device, a chip, a network card and equipment. BACKGROUND

[0002] In the technical field of chips, a Link Aggregation Group (LAG) bundles multiple physical network interfaces into a logical interface, thereby increasing link bandwidth, improving link reliability and achieving load balancing.

[0003] In related technologies, hardware LAG offloading is achieved by offloading the kernel Network Interface Bonding (BOND) configuration on the host side to the network card hardware side through a private kernel network driver. When implementing hardware LAG offloading, the network card hardware needs to rely on the network protocol stack of the host kernel to process protocol packets, and by configuring two or more physical function (PF) devices to a BOND group in the kernel, and offloading the private kernel network driver to the firmware side of the network card hardware.

[0004] However, when implementing hardware LAG offloading in the above manner, the PF device needs to be taken over by the kernel network driver. In order for the user process to pass through the kernel protocol stack and the network card directly, the kernel network driver can be exited first, and then taken over by the user state through a Virtual Function I / O (VFIO) method. This requires enabling a certain PF device of one of the BOND group members to Single Root I / O Virtualization (SRIOV) to generate a Virtual Function (VF) device, and then providing the VF device to the user state to take over in the VFIO manner. Therefore, the hardware LAG offloading in related technologies cannot directly take over the PF device by the user state driver without starting single root input / output virtualization. SUMMARY

[0005] Therefore, it is necessary to provide a hardware link aggregation deployment method, device, chip, equipment, network interface card, storage medium and program product capable of directly taking over a physical function device by a user state driver without starting single root input / output virtualization in view of the above technical problems.

[0107] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0108] First, the related art will be described below.

[0109] In chip technology, a Link Aggregation Group (LAG) bundles multiple physical network interfaces into one logical interface, thereby increasing link bandwidth, improving link reliability, and achieving load balancing.

[0110] Through the LAG technology, multiple physical network interfaces corresponding to physical links can be bundled into one whole, and when a certain physical link fails, traffic can be automatically switched to other normal links in the LAG, thereby ensuring the continuity of the service. At the same time, in the process of data transmission, the LAG can distribute traffic to each member link in the LAG according to a preset traffic distribution algorithm, thereby achieving effective utilization of bandwidth.

[0111] In the related art, hardware LAG offloading is achieved by offloading the kernel's network card aggregation (Network Interface Bonding, BOND) configuration to the network card hardware side through a private kernel network driver on the host side. Currently, in addition to offloading the complex network protocol stack, the network card hardware needs to rely on the network protocol stack of the host kernel to process protocol packets when implementing hardware LAG offloading. Two or more physical function (Physical Function, PF) devices are configured to a BOND group through the private kernel network driver, and then the BOND group is offloaded to the firmware side of the network card hardware.

[0112] The network card hardware can include an intelligent network or a data processing unit (Data Processing Unit, DPU).

[0113] However, when the hardware LAG offload is achieved by the above manner, the PF device needs to be taken over by the network driver of the kernel, in order for the user process to pass the service data through the kernel protocol stack and the network card, the kernel network driver can be exited first, and then the user state is taken over through the virtual function input / output (Virtual Function I / O, VFIO) mode.

[0114] It should be understood that in direct memory access, virtual function input / output (Virtual Function I / O, VFIO) plays a key role. Through input / output memory management unit (Input / Output Memory Management Unit, IOMMU) mapping, VFIO can map the direct memory access (Direct Memory Access, DMA) physical memory address of the device to the user state. Thus, the user state program has the ability to independently control data transmission, and allows the user state program to register an interrupt processing function by itself, and realizes the function of the device driver in the user state. Through VFIO, device pass-through can be realized, so that the user state driving device can directly interact with the network card hardware, successfully avoiding part of the processing flow of the kernel protocol stack, and significantly improving the efficiency and flexibility of data transmission.

[0115] In the scenario where the user state traffic is carried on the hardware LAG, since the PF device has been taken over by the kernel network driver of the host side as a BOND group member, it is necessary to enable single root I / O virtualization (Single Root I / O Virtualization, SRIOV) for a certain PF device of one of the BOND group members to generate a virtual function (Virtual Function, VF) device, and then provide the VF device for the user state driving in the VFIO mode. Therefore, the hardware LAG offload in the related art cannot directly take over the PF device by the user state driving without starting single root I / O virtualization.

[0116] To solve the above technical problems, the embodiments of the present application provide a hardware link aggregation deployment method, device, chip, equipment, network interface card, storage medium and program product. When the physical function devices in the created network card aggregation group all have the member capability of the link aggregation group, the host device sends a creation message of the link aggregation group to the network card device, thereby activating the representative port device mapped by the link aggregation group, and the representative port device is used to provide the user state driving in the virtual function input / output mode for control, and the service traffic is directly carried on the aggregation link group of the network card device. Since it is not necessary to enable single root I / O virtualization for a certain physical function device in the network card aggregation group, the physical function device can be directly taken over by the user state driving without starting single root I / O virtualization.

[0117] The hardware link aggregation deployment method provided by the embodiments of the present application can be applied to the application environment as shown in Figure 1 . A user inputs a network card aggregation configuration request to the host device 101, and the host device 101 creates a network card aggregation group in response to the network card aggregation configuration request, wherein the network card aggregation group includes at least one physical function device. Subsequently, the host device 101 sends a creation message of a link aggregation group corresponding to the network card aggregation group to the network card device 102 in the case that the unloading condition of the network card aggregation group is met, wherein the unloading condition of the network card aggregation group includes that each of the at least one physical function device has the member capability of the link aggregation group. The network card device 102 activates a representative port device mapped by the link aggregation group and sets the link aggregation group to an unloaded state in response to the creation message of the link aggregation group, and the representative port device is used for the user mode driver of the host device to control in the manner of virtual function input and output.

[0118] Wherein, the above-mentioned host device 101 and network card device 102 can be two devices interacting with each other, or can be integrated in a DPU, and the embodiments of the present application do not limit this.

[0119] Figure 2 The principle diagram of the hardware link aggregation deployment method provided by the embodiments of the present application is as shown in Figure 2 . The user mode of the host device side maps the PF device as a representative device (LAG0 REP PF2) of a link aggregation group (LAG0). After the host device side core network card aggregation group (BOND0) is unloaded to the firmware of the network card device, the representative port device (LAG0 REP PF2) mapped by the link aggregation group (LAG0) is activated, and the representative port device (LAG0 REP PF2) is used for the user mode driver of the host device to control in the manner of virtual function input and output, so as to realize the transmission of service traffic on the link aggregation group, so as to achieve the purposes of increasing link bandwidth, improving link reliability and realizing load balancing.

[0120] In an exemplary embodiment, as shown in Figure 3 , a hardware link aggregation deployment method is provided, and the host device and the network card device in Figure 1 are taken as examples for illustration. The hardware link aggregation deployment method includes S201 to S203.

[0121] S201, the host device creates a network card aggregation group in response to a network card aggregation configuration request.

[0122] In some embodiments, the above network card aggregation configuration request is used to instruct the host device to create a network card aggregation group (BOND) in the kernel configuration. The network card aggregation configuration request can indicate the aggregation mode of the network card aggregation group, the identification information of the network card aggregation group, the member port of the network card aggregation group, etc.

[0123] Among them, the network card aggregation group includes at least one physical function (Physical Function, PF) device.

[0124] For example, a user can create a network card aggregation group with identification information BOND0 by sending a network card aggregation configuration request to the host device, and then add two PF devices as master members in BOND0, including PF0 and PF1. Finally, set the aggregation mode of BOND0 to Link Aggregation Control Protocol (LACP) mode (i.e., mode 4).

[0125] S202, the host device sends a creation message of the link aggregation group corresponding to the network card aggregation group to the network card device if the offloading condition of the network card aggregation group is met.

[0126] In this step, after the host device creates the network card aggregation group, it can be determined whether the offloading condition of the network card aggregation group is met. If the offloading condition of the network card aggregation group is not met, the deployment of the hardware link aggregation is ended. If the offloading condition of the network card aggregation group is met, the host device sends a creation message of the link aggregation group corresponding to the network card aggregation group to the network card device.

[0127] It should be understood that the embodiments of the present application do not limit the offloading condition of the network card aggregation group. In some embodiments, the offloading condition of the network card aggregation group includes that at least one physical function device has the member capability of the link aggregation group. That is, when the physical function devices in the same network card aggregation group all have the member capability of the link aggregation group, the host device can send a creation message of the link aggregation group to the network card device to deploy the hardware link aggregation group.

[0128] Among them, the physical function devices all have the member capability of the link aggregation group, that is, the network card device associated with the physical function device has the capability of executing link aggregation logic directly at the hardware level without relying on the host and kernel protocol stack.

[0129] For example, the above creation message of the link aggregation group can be generated by converting the information of the network card aggregation group and the member information in the network card aggregation group.

[0130] S203, the network card device activates the representative port device mapped by the link aggregation group and sets the link aggregation group to an offloaded state in response to the creation message of the link aggregation group.

[0131] In this step, when the network card device receives the creation message of the link aggregation group, the representative port device mapped by the link aggregation group can be activated in response to the creation message of the link aggregation group, and the link aggregation group is set to an offloaded state.

[0132] The representative port device can be a pre-configured physical function device, which is a representative port (REP) of a corresponding group of link aggregation groups, and is a PF device of a Peripheral Component Interconnect express (PCIe) type.

[0133] It should be understood that, since the representative port device is mapped as the representative device of the link aggregation group, the host device user mode driver can be controlled by the representative port device in the VFIO manner after the network card device activates the representative port device mapped by the link aggregation group in response to the creation message of the link aggregation group, and the service traffic is directly carried on the aggregation link group of the network card device, without the need to enable SRIOV for a certain physical function device in the network card aggregation group, thereby realizing that the user mode driver directly takes over the physical function device without starting SRIOV, and increasing link bandwidth, improving link reliability, and realizing load balancing.

[0134] In some embodiments, the creation message of the link aggregation group includes member link information of the link aggregation group. Correspondingly, the network card device can modify the correspondence between the physical port and the link aggregation group in the receive port table after receiving the creation message of the link aggregation group.

[0135] The member link information of the link aggregation group is used to modify the correspondence between the physical port and the link aggregation group in the receive port table of the network card device. The physical port can be a receive (RX) port.

[0136] For example, the member link information of the link aggregation group (BOND0) can indicate the corresponding receive (RX) port, for example, it can indicate physical port 0 (physical port 0) and physical port 1 (physical port 1). Then, in the RX port table, the firmware of the network card device will correspond physical port 0 and physical port 1 to BOND0 respectively.

[0137] In some embodiments, after sending the creation message of the link aggregation corresponding to the network card aggregation group to the network card device, if the aggregation mode corresponding to the link aggregation group is the LACP mode, the network card device can create the flow table corresponding to the link aggregation group. Subsequently, the network card device sends the LACP protocol packet to the host device, and the LACP protocol packet is used to negotiate the active member of the network card aggregation group. Finally, the host device updates the state of the negotiated active member to the active link state of the link aggregation group, and sends the information of the active member to the network card device, and the information of the active member is used to set the register corresponding to the link aggregation group.

[0138] In the LACP mode, the multiple physical links of the two end devices (e.g., the host and the switch) can be bound as a logical aggregation link through dynamic negotiation.

[0139] For example, in the preset mode number, the LACP mode can correspond to mode 4. When the network card device detects that the aggregation mode of the created network card aggregation group is mode 4, the firmware of the network card device can create the flow table corresponding to the link aggregation group, so that the kernel network protocol stack of the host device can receive the LACP protocol packet. Through the interaction of the LACP protocol packet, the negotiation of the active member of the network card aggregation group can be completed.

[0140] For example, after the BOND group negotiates the active member, the kernel network of the host device can update the state of the active member to the active link (physical port) state of the link aggregation group, and send the information of the active member to the network card device to inform the network card device of the active member in the active link (physical port) state. After receiving the information of the active member, the network card device can set a series of registers related to the link aggregation group to create the relationship between the link aggregation group and the active member (physical port), so that the link aggregation group on the network card device side is in the active state.

[0141] In some embodiments, in response to the network card aggregation deletion request, the host device can also send a deletion message of the link aggregation group to the network card device. Subsequently, in response to the deletion message of the link aggregation group, the network card device deletes at least one of the setting information in the register corresponding to the link aggregation group and the flow entry of the at least one physical function device in the network card aggregation group in the flow table.

[0142] For example, the user can send a network card aggregation deletion request to the host device to instruct the pursuit device to delete the kernel network card aggregation group (BOND0). Then, the host device converts the network card aggregation deletion request into a deletion message of a link aggregation group (LAG0) corresponding to the network card aggregation group, and sends the deletion message of the link aggregation group (LAG0) to the network card device. After the firmware of the network card device receives the deletion message of the link aggregation group (LAG0), the firmware can delete the setting message in the LAG0 related register, and delete the flow table entry of the protocol packet of PF0 and PF1 in BOND0, so that all the packets sent to LAG0 will be discarded by the network card device.

[0143] The hardware link aggregation deployment method provided in the embodiments of the present application responds to a network card aggregation configuration request to create a network card aggregation group, and the network card aggregation group includes at least one physical function device. In the case that an offloading condition of the network card aggregation group is met, a creation message of a link aggregation group corresponding to the network card aggregation group is sent to a network card device. The offloading condition of the network card aggregation group includes that at least one physical function device has a member capability of the link aggregation group. The creation message of the link aggregation group is used to instruct the network card device to activate a representative port device mapped by the link aggregation group and set the link aggregation group to an offloaded state. The representative port device is used for a user mode driver of the host device to control in a virtual function input / output manner. In the embodiments of the present application, when the physical function devices in the created network card aggregation group all have the member capability of the link aggregation group, the creation message of the link aggregation group is sent to the network card device, so as to activate the representative port device mapped by the link aggregation group, and the representative port device is used for the user mode driver to control in the virtual function input / output manner. The service traffic is directly carried on the aggregation link group of the network card device. Since a single root input / output virtualization of a certain physical function device in the network card aggregation group is not enabled, the user mode driver can directly take over the physical function device without starting the single root input / output virtualization.

[0144] In the present application, since the user mode driver directly takes over the physical function device without starting the single root input / output virtualization, the maintenance cost is lower. The user can take over the representative port device in a VFIO manner without starting the single root input / output virtualization, so that the service traffic of the user mode process can be directly forwarded on the link of the LAG of the network card device without passing through the kernel protocol stack, and the flexibility of user deployment is provided.

[0145] The firmware flow processing after the host device controls the representative port device is described below. Figure 4 Another signaling interaction diagram of the hardware link aggregation deployment method provided in the embodiments of the present application is shown in FIG. 3. Figure 4 The hardware link aggregation deployment method includes S301 to S307.

[0146] S301, the host device creates a network card aggregation group in response to a network card aggregation configuration request.

[0147] S302, the host device sends a creation message of a link aggregation group corresponding to the network card aggregation group to the network card device in the case that the unloading condition of the network card aggregation group is met.

[0148] S303, the network card device activates a representative port device mapped by the link aggregation group and sets the link aggregation group to an unloaded state in response to the creation message of the link aggregation group.

[0149] S304, the host device sends an attribute acquisition request of the representative port device to the network card device in a port startup stage of the representative port device.

[0150] S305, the network card device sends attribute information of the representative port device to the host device.

[0151] The attribute acquisition request is used to acquire the attribute information of the representative port device, and the attribute information is used to reflect the hardware capability of the representative port device, including indication information of whether a port corresponding to the representative port device is a representative port of a LAG, and forwarding domain information of the representative port device.

[0152] The forwarding domain information of the representative port device can be identification information of the LAG mapped by the representative port device, and the forwarding domain information of other physical function devices other than the representative port device can be a physical port ID.

[0153] Correspondingly, after the user-mode network driver of the host device takes over the representative port device in the VFIO mode, the user-mode network driver can send the attribute acquisition request of the representative port device to the network card device in a startup stage of the representative port device, so as to receive the attribute information of the representative port device sent by the network card device to the host device, and determine whether the attribute information is a representative port of a LAG and the forwarding domain of the representative port device.

[0154] S306, the host device sends setting indication information of a flow diversion entry of the representative port device to the network card device according to the attribute information of the representative port device.

[0155] The user-mode network driver of the host device can determine that the representative port device is a representative port of a LAG and determine the forwarding domain of the representative port device based on the attribute information of the representative port device after the user-mode network driver is loaded, and can send the setting indication information of the flow diversion entry of the representative port device to the network card device, so as to set the flow diversion entry of the representative port device based on the forwarding domain of the representative port device.

[0156] The flow diversion entry can include a plurality of flow diversion rule information for condition matching and processing of traffic of the representative port device.

[0157] S307, the network card device sets the flow steering rules of the representative port device in the receiving direction and the sending direction in the flow steering entry of the representative port device in response to the setting indication information.

[0158] The flow steering rules include a rule of matching a flow condition and a rule of processing the flow.

[0159] It should be understood that since the firmware of the network card device determines that the forwarding domain of the representative port device is the LAG domain, accordingly, the firmware of the network card device iterates all member links in the LAG, and sets the flow steering rules of the representative port device in the receiving direction (RX) and the sending direction (TX) in the flow steering entry of the representative port device based on the setting indication information, to ensure that the flow steering rules take effect in the range of multiple member links in the LAG group associated with the representative port device.

[0160] For example, since the physical port of each corresponding physical function device in the LAG is assigned a corresponding identifier in advance and is bound to the identifier of the LAG, when the firmware of the network card device receives the setting indication information of the flow steering entry, the flow steering rules can be set in the receiving direction and the sending direction, so that the service data entering from any physical port can be correctly identified and forwarded to the corresponding representative port device of the LAG.

[0161] It should be noted that after the setting of the flow steering rules is completed, the LACP packet received by the physical port is still sent to the physical function device of the kernel of the host device, and is processed by the kernel network protocol stack.

[0162] In some embodiments, on the network card forwarding chip, a default flow steering rule of the corresponding representative port device in the sending direction (TX) can also be set, which takes effect in the LAG forwarding domain and the destination port is not LAG.

[0163] In some embodiments, when the user mode driver of the host device exits the control of the representative port device, the host device can send a notification message to the firmware of the network card device to instruct the firmware of the network card device to delete the flow steering entry and / or the flow steering rules in the receiving direction and the sending direction. At this time, the representative port device does not receive any packet in the receiving direction, and all packets sent in the sending direction are discarded by the network card device.

[0164] It should be noted that S304 to S307 can be after S301 to S303, can be before S301 to S303, and the embodiments of the present application do not limit this. In some embodiments, the user state of the host device can first control the representative port device in the VFIO mode and set the flow diversion rule. At this time, the traffic or message cannot be temporarily transmitted, and the user can use the Internet Protocol Link (IP Link) command to configure the network card aggregation group, and offload the hardware LAG to the fixed network card device.

[0165] The configuration of the representative port device will be described below. Figure 5 Another signaling interaction diagram of a hardware link aggregation deployment method provided by the embodiments of the present application is shown in Figure 5 The hardware link aggregation deployment method includes S401 to S413.

[0166] S401, the network card device increases the physical function entry of the representative port device of the link aggregation group in the device data of the storage file in response to the setting request of the representative port device.

[0167] In the present application, the physical function entry of the representative port device of the link aggregation group in the device data of the storage file can be increased by sending a setting request of the representative port device to the network card device, so as to set the representative port device mapped by the link aggregation group.

[0168] The storage file can be a Non-Volatile Memory (NVM) configuration file.

[0169] For example, through the setting request of the representative port device, the device data of the NVM configuration file can be configured, the physical function entry of the representative port device of the link aggregation group is increased, and the physical function device in a certain PCIe is defined as the representative port of a certain hardware LAG.

[0170] For example, a PF entry can be added in the NVM configuration file as the physical function entry of the representative port device of the link aggregation group. In the PF entry, the identifier of the representative port device is 2, the corresponding LAG identifier is 0, and the indication message (lag rep flag) of the LAG representative port device is set to 1.

[0171] In some embodiments, the physical function entry of the representative port device of the link aggregation group also includes specific parameter settings, for example, a mapping relationship parameter between the physical function device and the LAG. That is, the physical function entry can not only include the identifier information of the physical function device and the related parameters of the LAG, but also include the mapping relationship parameter between the physical function device and the LAG.

[0172] The identification information of the physical function device can include a device ID, a manufacturer identification code ID, and the like of the physical function device, and the representative port device can be accurately identified through the identification information of the physical function device. The related parameters of the LAG can include an LAG ID, a member link list, and the like, and the composition structure and characteristics of the hardware LAG can be described in detail through the related parameters of the LAG.

[0173] The mapping relationship parameter between the physical function device and the LAG binds the representative port device and the corresponding LAG in one-to-one through specific syntax and rules, so that the connection between the representative port device and the LAG can be quickly and accurately established according to the physical function item in the running process.

[0174] S402, the network card device reads the device data in the storage file after detecting that the network card device is started.

[0175] For example, after detecting the start, the network card device can first scan the NVM configuration file in the preset position of the storage medium. Then, the network card device reads and analyzes each parameter in the NVM configuration file line by line according to specific file parsing rules to obtain the device data.

[0176] S403, the network card device associates the forwarding domain and the physical connection state of the representative port device with the link aggregation group according to the device data.

[0177] For example, the configurations of all the physical function devices supported by the network card are saved in the device data of the NVM configuration file. Correspondingly, the firmware of the network card device can load the configuration data of all the physical function devices in the device data during the initialization process after the start, so as to associate the forwarding domain and the physical connection state of the representative port device with the link aggregation group.

[0178] For example, for the physical function device of the representative port device, the forwarding domain can be set as the corresponding LAG domain, and the member links included in the LAG domain are determined by the configuration of the LAG itself. Correspondingly, the physical connection state of the representative port device is associated with the LAG. After the physical connection state of the representative port device is associated with the LAG, only when all the member links of the LAG are disconnected, the firmware of the network card device will change the physical connection state of the representative port device from the connected state to the disconnected state, and will notify the user state of the host device in the form of an event.

[0179] For example, for the physical function device of the non-representative port device, the forwarding domain can be set as a certain physical link, and correspondingly, the physical connection state of the physical function device of the non-representative port device can be consistent with the state of the corresponding physical link.

[0180] S404, when detecting that the network card device is started, the host device probes the physical function device configured in the network card device and obtains the identification information of the detected physical function device.

[0181] In some embodiments, when detecting that the network card device is started, the host device can determine the physical function device configured in the network card device through a probing (prob) mechanism.

[0182] The probing (prob) mechanism can be a process of scanning and discovering, driver matching, resource allocation and hardware activation of the physical function device in the network card device by the host device, so that the kernel in the host device fully controls the network card and determines the physical function device configured in the network card device.

[0183] S405, the host device determines the type of the detected physical function device according to the identification information of the detected physical function device.

[0184] The type of the physical function device can include the type of the representative port device and the type of the non-representative port device.

[0185] For example, the host device can distinguish whether the physical function device is of the type of the representative port device or the type of the non-representative port device based on the identification information of the physical function device, and the device identification information of the type of the representative port device can be set with a special flag bit.

[0186] S406, the host device loads the kernel network driver of the detected physical function device in the case that the type of the detected physical function device is not the representative port device of the link aggregation group.

[0187] In some embodiments, in the case that the type of the detected physical function device is the representative port device of the link aggregation group, the host device does not load the kernel network driver of the detected physical function device by default. In the case that the type of the detected physical function device is not the representative port device of the link aggregation group, the host device loads the kernel network driver of the detected physical function device. In this way, the number of physical function devices and the number of physical ports seen by the user through the IP link display (ip link show) information in the kernel remain consistent.

[0188] It should be understood that the embodiments of the present application do not limit how the kernel network driver of the detected physical function device is loaded. In some embodiments, the host device can send a capability information acquisition request of the detected physical function device to the network card device. The network card device then sends the hardware capability information of the detected physical function device to the host device. The host device initializes the kernel network driver of the detected physical function device according to the hardware capability information, and obtains the setting information of the physical function device. Finally, the host device sends the setting information of the detected physical function device to the network card device, and the network card device sets the transmit-receive queue and the flow table of the detected physical function device according to the setting information of the physical function device.

[0189] The hardware capability information can include forwarding domain information of the physical function device, offload capability information of the PF hardware physical function device, and LAG identification information to which the physical function device belongs.

[0190] For example, based on the forwarding domain information of the physical function device, the offload capability information of the PF hardware physical function device, and the LAG identification information to which the physical function device belongs, the host device initializes the kernel network driver of the detected physical function device, determines the setting information of the physical function device, and then sends the setting information of the physical function device to the network card device to set the transmit-receive queue and the flow table of the detected physical function device.

[0191] The setting information of the physical function device includes the setting information of the transmit-receive queue and the device of the flow table. For example, by setting the transmit-receive queue and the flow entry in the flow table, the traffic forwarding of the physical function device is one-to-one corresponding to the physical link corresponding thereto. At this time, the physical function device (for example, PF0 and PF1) can normally transmit and receive packets, and the link connection state is one-to-one corresponding to the physical link (for example, physical port 0 and physical port 1) corresponding thereto.

[0192] S407, the host device creates a network card aggregation group in response to a network card aggregation configuration request.

[0193] S408, the host device sends a creation message of a link aggregation group corresponding to the network card aggregation group to the network card device under the condition that the offload condition of the network card aggregation group is met.

[0194] S409, the network card device activates the representative port device mapped by the link aggregation group and sets the link aggregation group to an offloaded state in response to the creation message of the link aggregation group.

[0195] S410, the host device sends an attribute acquisition request of the representative port device to the network card device in a port startup stage of the representative port device.

[0196] S411, the network card device sends attribute information of the representative port device to the host device.

[0197] S412, the host device sends setting indication information of the representative port device to the network card device according to the attribute information of the representative port device.

[0198] S413, the network card device sets the flow steering rules of the representative port device in the receiving direction and the sending direction in the flow steering entry of the representative port device in response to the setting indication information.

[0199] In the present application, since the association between the representative port device and the LAG can be determined by loading the NVM configuration file, the forwarding domain of the representative port device is fixed regardless of whether the LAG is successfully unloaded. Therefore, there is no sequence between the kernel BOND configuration and the user state network drive control representative port operation. Similarly, if the user wants to delete the BOND, it is not necessary to first release the control of the representative port device in the user state network drive. The firmware of the network card device can still correctly release the related forwarding resources and will not cause resource residue. Since there is no need for the user to change the existing configuration habit, the network drive does not load the representative port device, and the number of physical function devices queried by the user in the kernel state remains consistent with the number of physical network ports. Correspondingly, if the representative port device is not needed, the device can also not be loaded, and the PF function and the SRIOV function of the kernel are not affected.

[0200] The hardware link aggregation deployment method provided in the embodiments of the present application creates a network card aggregation group in response to a network card aggregation configuration request, the network card aggregation group including at least one physical function device; in the case that the unloading condition of the network card aggregation group is met, a creation message of a link aggregation group corresponding to the network card aggregation group is sent to the network card device; wherein the unloading condition of the network card aggregation group includes that each of the at least one physical function device has a member capability of the link aggregation group; the creation message of the link aggregation group is used to instruct the network card device to activate a representative port device mapped by the link aggregation group and set the link aggregation group to an unloaded state; the representative port device is used for the user state drive of the host device to control in a virtual function input and output manner. In the embodiments of the present application, when each of the physical function devices in the created network card aggregation group has the member capability of the link aggregation group, the creation message of the link aggregation group is sent to the network card device, so as to activate the representative port device mapped by the link aggregation group, and the user state drive is controlled in a virtual function input and output manner by the representative port device, and the service traffic is directly carried on the aggregation link group of the network card device. Since it is not necessary to enable single root input and output virtualization of a certain physical function device in the network card aggregation group, the user state drive can directly take over the physical function device under the condition that the single root input and output virtualization is not started.

[0201] It should be understood that although the steps in the flowcharts involved in the above embodiments are shown in sequence according to the arrows, the steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, the execution of the steps is not strictly limited in sequence, and the steps can be executed in other orders. Moreover, at least some of the steps in the flowcharts involved in the above embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of the steps or stages is not necessarily sequential, but can be alternately executed with other steps or steps or stages in other steps.

The problem-solving implementation scheme provided by the apparatus is similar to the implementation scheme described in the above method, and therefore the specific limitations in one or more hardware link aggregation deployment apparatus embodiments provided below can refer to the limitations of the hardware link aggregation deployment method on the host device side described above, and will not be described here again.

[0212] In some embodiments, the first sending module 502 is further configured to send a deletion message of the link aggregation group corresponding to the network card aggregation group to the network card device in response to a network card aggregation deletion request.

[0213] The deletion message of the link aggregation group is used to instruct the network card device to delete at least one of the setting information in the register corresponding to the link aggregation group and the steering entry of the at least one physical function device in the network card aggregation group in the steering table.

[0214] In some embodiments, the first sending module 502 is further configured to send an attribute acquisition request of the representative port device to the network card device in a port startup stage of the representative port device, and send setting indication information of the steering entry of the representative port device to the network card device according to the attribute information of the representative port device.

[0220] The modules in the deployment apparatus for hardware link aggregation described above can be implemented in whole or in part by software, hardware, or a combination thereof. The modules described above can be embedded in a processor in a hardware form or independent of the processor in the computer device, or stored in a memory in the computer device in a software form, so as to be invoked and executed by the processor to perform the operations corresponding to the modules.

[0221] Based on the same inventive concept, the embodiments of the present application further provide a deployment apparatus for hardware link aggregation for implementing the deployment method of hardware link aggregation on the side of the network card device. The apparatus provides a solution to the problem similar to the implementation solution described in the above method, and therefore the specific limitations in one or more deployment apparatus embodiments for hardware link aggregation provided below can be referred to the limitations of the deployment method of hardware link aggregation on the side of the network card device described above, which will not be repeated here.

[0222] In one exemplary embodiment, as shown in Figure 7 a deployment apparatus 600 for hardware link aggregation is provided, comprising a second receiving module 601, a second processing module 602, and a second sending module 603, wherein:

[0223] The second receiving module 601 is configured to receive a creation message of a link aggregation group corresponding to a network card aggregation group sent by a host device, in a case where an offloading condition of the network card aggregation group is met, the network card aggregation group comprising at least one physical function device, the offloading condition of the network card aggregation group comprising that at least one physical function device has a member capability of the link aggregation group.
