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
