RTL8125B 2.5G network card

As shown in the picture, 2.5G can be identified, but because the broadband is only Gigabit, the speed test can only run up to Gigabit.
The RTL8125BG sold on the Lichuang Mall and the RTL8125B with the crab logo can be used in actual tests. A chip with already flashed firmware can directly work normally. Newly purchased chips need to flash the firmware once.
Wake on LAN is connected, but not tested.
When placing an order in Jiali, you need to choose the gold finger to the hypotenuse, choose the required impedance, and choose the free 7628 structure for the laminate structure.
The firmware burning file is in the attachment. After decompression, modify the corresponding cfg file (it can be used directly without modification, in which the first line NODEID is the MAC address). Start with the DOS system (recommend the micro PE DOS toolbox to enter pure DOS) and enter Run PG8125 /efuse /w on the previously extracted folder.
