Description and Notes

This card uses the same Realtek 8125 chip that’s in the Rosewill RC20001 2.5 Gbps card I tested, but the difference is it has two of them!

Between those two chips and the Pi is an ASMedia 1182 PCI Express 2.0 1x packet switch, which allows the two Realtek chips to work with the Pi over its single PCIe 1x lane.

The Realtek chips on this card require the Realtek 8125 driver, which can be compiled or cross-compiled into the Pi kernel.

The driver can be selected with menuconfig in the path:

Device Drivers
  > Network device support
    > Ethernet driver support
      > Realtek devices
        > Realtek 8169/8168/8101/8125 ethernet support

I am still testing the card’s performance, and will update this page after that testing is complete.
