• Port ordering above is from leftmost RJ45 on board when viewing the front-panel
• If 'net.ifnames=0' kernel parameter is specified network interfaces on enumerated busses such as pci/usb are numbered sequentially (ie eth1 instead of enp6s0). See ​Predictable Interface Names for details
  • Bootloader variable example:

    u-boot=> print bootargs 
    bootargs=net.ifnames=0
    u-boot=> 
    

• For boards like the GW740x which have a multi-port GbE switch, bandwidth is shared across the downstream ports
