Our Plugable.com usb3me-hub3me usb-to-ethernet  network adapters are
named  by default as enx${MacAddress}  which  with the NULL ‘\0’  at
the end pushes  it to 16 characters.

  enx${MacAddress}.3 does not work to get to vLan 3 because of the
name is too long.

So will have to use udev rules to rename these devices so that i can
get them on the switch management vLan i  locked myself out  of …. yet
again.
