Configure Ethernet with RJ45 port

Ethernet/RJ45 port is enabled as a downstream port of PCIe to USB controller (renesas). Ensure that the renesas_usb_fw.mem file is available at the /lib/firmware directory.

If the renesas_usb_fw.mem firmware isn’t available at the /lib/firmware directory, then update USB and Ethernet controller firmware.

To check if the USB to Ethernet controller is enumerated, run the following command:

lsusb

Connect an RJ45 cable to the device:

Check the Ethernet IP address:

ip address

10.219.0.106 is the IP address.
