Well you can always try something like this.
>$ dmesg |grep eth0
eth0: VIA Networking Velocity Family Gigabit Ethernet Adapter
eth0: Ethernet Address: 00:50:8D:D1:28:6B
eth0: Link autonegation speed 100M bps full duplex
Or course changing the eth0 to eth1 or such if different even eth* for any ethernet card detected.
