Why not use the DMI External Connector Designator. That's what
the manufacturer provides to identify external ports after all.
Some examples for kit I have to hand:

MacMini
   eth0 00:16:CB:xx:xx:3D Ethernet

MacBook Pro
   eth0 00:17:F2:xx:xx:2E RJ-45

Acer Altos R300 (no external connector designation)
   eth0 00:00:E2:xx:xx:FE
   eth1 00:00:E2:xx:xx:FF

Acer Altos R510
   eth0 00:0E:0C:xx:xx:CF NIC2/2
   eth1 00:0E:0C:xx:xx:CE NIC1/2

IBM xSeries 343
   eth0 00:0E:0C:xx:xx:D9 NIC2/2
   eth1 00:0E:0C:xx:xx:D8 NIC1/2

The results aren't too bad, especially for those last two
Intel motherboards where the ethN and physical port orders
are reversed.
