      Biosdevname is a udev helper that looks at various BIOS tables to

      figure out what the actual hardware names are for Ethernet ports

      and renames the ports accordingly. This has the advantage of

      always referring to the same port regardless of system or

      hardware changes that might otherwise alter the typical ethX

      naming.
