Description
Technical Field
[0001] The utility model belongs to the field of electronic technology, and in particular relates to a MAC address updating device. Background Art
[0002] In domestic processor platform devices, network controllers mostly use network chips such as Intel's 82580EB / 82580DB / WG82574 / I350 and domestic Netcom WX1860AL4 / WX1860AL2. However, the network chips of these two companies are very expensive, resulting in relatively high platform hardware costs. The RTL8111 series network controllers are very cheap. If they are used in domestic platform devices, the cost of the entire device can be greatly reduced, making domestic platform devices more competitive.
[0003] However, because the RTL8111 series controller uses internal reserved empty byte positions as storage space for MAC address data, it is impossible to use a programmer to complete the MAC update in an offline state, but it is necessary to use a burning tool to burn the MAC address online. However, Realtek does not provide burning tools for domestic hardware architectures such as Shenwei and Feiteng, resulting in the inability to directly use the chip-level solution of the RTL8111 series network controller on domestic hardware platforms.
