Obviously, the drawings described below are only embodiments of the present application.

[0038] From the hardware perspective, the Ethernet interface circuit is mainly composed of two parts: MAC (Media Access Control) controller and physical layer interface PHY (Physical Layer, PHY), such as Figure 1 shown. Figure 1 The DMA (Direct Memory Access) controller in the CPU is usually part of the CPU. Figure 1 The DMA controller is shown with a dotted line to indicate that the DMA controller may be involved in network port data transmission.

[0039] MAC and PHY work in the data link layer and physical layer of the OSI seven-layer model respectively. Among them, MAC (Media Access Control) is the media access control sublayer protocol. MAC can be a combination of a hardware controller and a MAC communication protocol. The MAC communication protocol is located in the lower half of the data link layer in the OSI seven-layer protocol, and is mainly responsible for controlling the physical medium that connects to the physical layer. When sending data, the MAC protocol can determine in advance whether the data can be sent. If it can be sent, some control information will be added to the data, and finally the data and control information will be sent to the physical layer in a specified format. When receiving data, the MAC protocol first determines whether the input information has a transmission error. If there is no error, the control information is removed and sent to the LLC (Logical Link Control) layer.

[0040] Since PHY integrates a lot of analog hardware, while MAC is a typical all-digital device, considering the chip area and analog / digital hybrid architecture, MAC is usually integrated into the microcontroller and PHY is left outside the chip. With the development of new product security technology, more flexible and higher density chip technology can realize the single-chip integration of MAC and PHY.

[0041] Devices with Ethernet interfaces usually support a variety of different MAC interface solutions, that is, they support a variety of different MAC function modes, such as SGMII, USXGMII and other MAC modes, and can also support multi-rate switching such as 100M, 1G, 2.5G, 5G, 10G, etc. A MAC function mode needs to be implemented through the corresponding configuration firmware and driver. When the Ethernet device needs to switch from one MAC function mode to another MAC function mode, the device needs to be powered off, and then the boot medium is re-burned with the firmware corresponding to another MAC function mode and the corresponding driver is switched to implement another MAC function mode.

[0042] like Figure 2As shown in the figure, when the Ethernet interface adopts the SGMII 1G interface solution, the required clock is a 100MHz clock. In order to realize the MAC interface mode, it is necessary to configure the hardware board-level design of the 100MHz clock, and then configure the software solution on the hardware board-level design, first configure the SGMII 1G firmware (configure the SGMII 1G MAC and serdes and other hardware configurations), then load the corresponding driver by loading the "SGMII" property description of the device tree, and finally load and start the operating system to realize the SGMII1G functional interface.

[0043] After implementing the SGMII 1G function, if you want to switch to the USXGMII 10G interface mode, you need to power off and replace the hardware board-level design of the 156.25MHz clock. After powering on, reconfigure the software solution on the hardware board-level design. First, configure the USXGMII 10G firmware (configure USXGMII 10G MAC and serdes and other hardware configurations), then load the corresponding driver by loading the "USXGMII" property description of the device tree, and finally load and start the operating system to implement the USXGMII 10G functional interface.

[0044] The above MAC function switching method requires powering off and reconfiguring the device, which is cumbersome to implement, complicated to operate, and has low switching efficiency.

[0045] In view of the above technical problems, an embodiment of the present application proposes a MAC function switching method, which can realize MAC function hot switching without powering off the Ethernet device, thereby reducing the complexity of MAC function switching and improving switching efficiency.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] An embodiment of the present application provides a MAC function switching method, which is applied to an Ethernet device, where the Ethernet device refers to a device with an Ethernet interface, such as a computer, a server, a router, a switch, etc.

[0048] In the Ethernet device, a processor and a memory are provided. The memory may refer to any type of memory used to store data in the Ethernet device, such as an internal memory, such as RAM (SRAM, DRAM), ROM (PROM, EPROM), an external memory, a buffer memory, a flash memory, etc. In an embodiment of the present application, the memory of the Ethernet device stores MAC hardware configuration information corresponding to a plurality of different MAC functional modes, and the MAC hardware configuration information includes MAC initialization configuration information (including MAC basic initialization information, MAC initialization clock, etc.) and serial deserializer configuration information (including serdes initialization information, clock configuration information, PLL (Phase Locked Loop, phase-locked loop) configuration information, etc.). For example, for various MAC functional modes such as SGMII 1G, SGMII 2.5G, USXGMII 5G, and USXGMII 10G, the MAC hardware configuration information corresponding to each of them is stored in the memory of the above-mentioned Ethernet device.

[0049] The processor in the Ethernet device is a device with data calculation, processing and control functions, such as a CPU on a computer or server, a controller or processor on a router or switch, etc. In the embodiment of the present application, the processing of the Ethernet device is used to execute the MAC function switching method proposed in the embodiment of the present application.

[0050] In order to implement the more efficient MAC function switching method proposed in the embodiment of the present application in the above-mentioned Ethernet device, the above-mentioned Ethernet device adopts a hardware board-level design common to the SGMII interface and the USXGMII interface, and the hardware clock adopts a 156.25MHz clock. Among them, in each embodiment of the present application, the hardware clock of the Ethernet device can be the clock of the entire Ethernet device, or it can be the clock provided by the Ethernet device for the Ethernet interface. In short, in the Ethernet device of the embodiment of the present application, the clock of the Ethernet interface is a 156.25MHz clock.

[0051] On the other hand, the operating system driver of the Ethernet device integrates MAC hardware configuration information, such as MAC initialization configuration information and serial deserializer configuration information, and the operating system can update the MAC hardware configuration information in the driver to the firmware.

[0052] Based on the above characteristics, the above Ethernet device can run random firmware when it is started, and then load the operating system to start running. Among them, the above random firmware refers to the firmware that loads and runs including any MAC hardware configuration information after the Ethernet device is powered on, without considering which MAC function mode will be adopted when the device is running. After the Ethernet device is started, the MAC function switching method proposed in the embodiment of the present application can be executed to update the MAC hardware configuration information in the operating system driver in the operating system to achieve the update of the MA hardware configuration information in the firmware.

[0053] See also Figure 3 As shown, the MAC function switching method proposed in the embodiment of the present application includes:

[0054] S101. Determine a corresponding target MAC functional mode according to a network rate, and determine a clock frequency corresponding to the target MAC functional mode.

[0055] The above network rate refers to the network rate required to be achieved by the MAC interface mode, that is, the network rate of the MAC function mode to be switched. Since different MAC function modes correspond to different network rates, such as SGMII 1G, SGMII 2.5G, USXGMII 5G, and USXGMII 10G, the corresponding network rates are 1G, 2.5G, 5G, and 10G, respectively. Therefore, in some cases, the purpose of switching the MAC function mode can be achieved by specifying or switching the network rate.

[0056] Exemplarily, the user can select the network rate of the Ethernet device by configuring the system. Accordingly, the processing of the Ethernet device can determine the network rate by reading the network rate configuration of the system. Then, based on the network rates corresponding to different MAC functional modes, the target MAC functional mode can be determined. In this embodiment, the above-mentioned target MAC functional mode includes but is not limited to any one of SGMII 1G, SGMII 2.5G, USXGMII 5G, and USXGMII 10G.

[0057] In some embodiments, the network rate of the Ethernet device is determined by the rate of the optical module or PHY chip to which the MAC interface is connected, so the processor can identify the network rate of the optical module or physical layer interface chip of the Ethernet device to determine the target MAC functional mode. That is, the MAC functional mode corresponding to the network rate of the optical module or physical layer interface chip of the Ethernet device is determined as the target MAC functional mode.

[0058] The above implementation can enable the Ethernet device to automatically determine the target MAC functional mode according to the network rate, thereby facilitating the subsequent automatic switching of the MAC functional mode.

[0059] After determining the target MAC function mode, the processor further determines the clock frequency required for the target MAC function mode. Each MAC function mode needs to work at a specific clock frequency, so the correspondence between each MAC function mode and the clock frequency can be determined in advance, and then after determining the target MAC function mode, the clock frequency corresponding to the target MAC function mode can be determined based on the above correspondence.

[0060] S102: Configure MAC hardware configuration information corresponding to the target MAC functional mode in the system driver of the Ethernet device.

[0061] As introduced in the above embodiment, the embodiment of the present application integrates MAC hardware configuration information in the driver of the operating system of the Ethernet device. Therefore, during the operation of the Ethernet device, the MAC hardware configuration information can be configured through the driver of the operating system, and then the MAC hardware configuration information in the Ethernet device firmware can be updated, so that the Ethernet device can achieve a specific MAC function mode.

[0062] Therefore, after determining the target MAC functional mode in step S101, the processor of the Ethernet device further configures MAC hardware configuration information corresponding to the target MAC functional mode in the startup driver of the Ethernet device.

[0063] Exemplarily, since MAC hardware configuration information corresponding to a plurality of different MAC functional modes is pre-stored in the memory of the Ethernet device, the processor may read the MAC hardware configuration information corresponding to the target MAC functional mode from the memory.

[0064] Then, the processor clears the original MAC hardware configuration information in the operating system driver, and then writes the MAC hardware configuration information corresponding to the target MAC functional mode into the operating system driver of the Ethernet device.

[0065] At this time, the MAC hardware configuration information in the operating system driver of the Ethernet device is updated to the MAC hardware configuration information corresponding to the target MAC functional mode. Further, the operating system can also update the MAC hardware configuration information in the Ethernet device firmware to the MAC hardware configuration information corresponding to the target MAC functional mode.

[0066] At this point, the MAC hardware configuration of the Ethernet device is already able to support the Ethernet device to run the target MAC function mode.

[0067] S103: Adjust the clock frequency of the Ethernet device to the clock frequency corresponding to the target MAC functional mode, and load the MAC function driver to switch the Ethernet device to the target MAC functional mode.

[0068] Specifically, since any MAC function mode needs to work at a specific clock frequency, and the clock provided by the Ethernet device for the Ethernet interface has only one clock frequency of 156.25MHz, in order to implement hot switching of different MAC function modes on the Ethernet device, it is necessary to make the clock of the Ethernet device meet the clock requirements of different MAC function modes.

[0069] In order to meet the clock frequency corresponding to the target MAC functional mode, the processor of the Ethernet device adjusts the clock frequency provided by the Ethernet device to the clock frequency corresponding to the target MAC functional mode.

[0070] For example, the processor may directly adjust the frequency provided by the Ethernet device so that the frequency of the clock provided by the Ethernet device is updated to the clock frequency corresponding to the target MAC functional mode.

[0071] In another embodiment, the processor may control the frequency division circuit to divide the clock provided by the Ethernet device so that the divided clock frequency is the clock frequency corresponding to the target MAC functional mode.

[0072] For example, assuming that the target MAC functional mode is SGMII 1G, the processor divides the clock provided by the Ethernet device into a clock of 156.25*8=1.25GHz, which is encoded by 8b / 10b to a 1G rate; if the target MAC functional mode is SGMII2.5G, the processor divides the clock provided by the Ethernet device into a clock of 156.25*20=3.25GHz, which is encoded by 8b / 10b to a 2.5G rate; if the target MAC functional mode is USXGMII 5G, the processor divides the clock provided by the Ethernet device into a clock of 156.25*33=5.15625GHz, which is encoded by 64b / 66b to a 5G rate; if the target MAC functional mode is USXGMII 10G, the processor divides the clock provided by the Ethernet device into a clock of 156.25*66=10.3125GHz, which is encoded by 64b / 66b to a 10G rate.

[0073] After having the clock frequency corresponding to the target MAC function mode, the processor further loads the MAC function driver, that is, loads the original MAC function driver, performs MAC initialization and packet sending and receiving configuration process, at which time the interface enables the Ethernet device to switch to the target MAC function mode.

[0074] When the Ethernet device is running in the above-mentioned target MAC functional mode, if the MAC functional mode needs to be switched again, the above-mentioned steps S101 to S103 can be executed again to implement the switching of the MAC functional mode again without powering off the Ethernet device.

[0075] It can be seen from the above introduction that the MAC function switching method proposed in the embodiment of the present application pre-stores MAC hardware configuration information corresponding to a plurality of different MAC function modes in the Ethernet device, such as MAC initialization configuration information and serial deserializer configuration information. Then, during the operation of the Ethernet device, the target MAC function mode to be switched is determined according to the network rate, and the clock frequency corresponding to the target MAC function mode is determined, and then the MAC hardware configuration information corresponding to the target MAC function mode is configured in the system driver of the Ethernet device; finally, the clock frequency of the Ethernet device is adjusted to the clock frequency corresponding to the target MAC function mode, and the MAC function driver is loaded to switch the Ethernet device to the target MAC function mode. The above-mentioned MAC function switching method pre-stores MAC hardware configuration information corresponding to a plurality of different MAC function modes in the Ethernet device, and when it is identified that the MAC function switching is required, the MAC hardware configuration information corresponding to the target MAC function mode is configured in the system driver of the Ethernet device, so as to realize the update of the system firmware and the driver, and then realize the hot switching of the MAC function. The above-mentioned MAC function switching process does not require the device to be powered off, nor does it require the firmware to be re-burned, and can realize automatic switching, and the switching efficiency is higher.

[0076] Corresponding to the above-mentioned MAC function switching method, the embodiment of the present application further proposes a MAC function switching device, which can be applied to an Ethernet device, wherein the Ethernet device stores MAC hardware configuration information corresponding to a plurality of different MAC function modes, wherein the MAC hardware configuration information includes MAC initialization configuration information and serial deserializer configuration information, see Figure 4 As shown, the MAC function switching device includes:

[0077] The mode determination unit 100 is used to determine the corresponding target MAC functional mode according to the network rate, and determine the clock frequency corresponding to the target MAC functional mode;

[0078] A configuration updating unit 110, configured to configure MAC hardware configuration information corresponding to the target MAC functional mode in a system driver of the Ethernet device;

[0079] The function switching unit 120 is used to adjust the clock frequency of the Ethernet device to the clock frequency corresponding to the target MAC function mode, and load the MAC function driver to switch the Ethernet device to the target MAC function mode.

[0080] In some implementations, the mode determination unit 100 determines the corresponding target MAC functional mode according to the network rate, including:

[0081] Identify the network rate of the optical module or physical layer interface chip of the Ethernet device;

[0082] Determine the target MAC function mode corresponding to the network rate of the optical module or physical layer interface chip.

[0083] In some implementations, the configuration updating unit 110 configures the MAC hardware configuration information corresponding to the target MAC functional mode in the system driver of the Ethernet device, including:

[0084] Obtain MAC hardware configuration information corresponding to the target MAC functional mode;

[0085] Clearing the MAC hardware configuration information in the system driver of the Ethernet device;

[0086] The MAC hardware configuration information corresponding to the target MAC functional mode is written into the system driver of the Ethernet device.

[0087] In some implementations, the function switching unit 120 adjusts the clock frequency of the Ethernet device to the clock frequency corresponding to the target MAC functional mode, including:

[0088] The clock frequency of the Ethernet device is divided so that the clock frequency of the Ethernet device is the clock frequency corresponding to the target MAC functional mode.

[0089] In some implementations, when the Ethernet device starts up, it runs random firmware and loads an operating system, wherein the random firmware includes any MAC hardware configuration information and serial deserializer configuration information.

[0090] In some implementations, the clock frequency of the Ethernet device is 156.25 MHz, and the target MAC functional mode includes any one of SGMII 1G, SGMII 2.5G, USXGMII 5G, and USXGMII 10G.

[0093] It should be understood that the units in the above devices can be implemented in the form of a processor calling software. For example, the device includes a processor, the processor is connected to a memory, and instructions are stored in the memory. The processor calls the instructions stored in the memory to implement any of the above methods or realize the functions of each unit of the device, wherein the processor can be a general-purpose processor, such as a CPU or a microprocessor, etc., and the memory can be a memory in the device or a memory outside the device. Alternatively, the units in the device can be implemented in the form of hardware circuits, and the functions of some or all units can be realized by designing the hardware circuits. The hardware circuit can be understood as one or more processors; for example, in one implementation, the hardware circuit is an ASIC, and the functions of some or all of the above units are realized by designing the logical relationship of the components in the circuit; for another example, in another implementation, the hardware circuit can be implemented by PLD, taking FPGA as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by the configuration file, so as to realize the functions of some or all of the above units. All units of the above devices can be implemented in the form of a processor calling software, or in the form of hardware circuits, or in part by a processor calling software, and the remaining part is implemented in the form of hardware circuits.

In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as an NPU, TPU, DPU, etc.
