Mine is different, but both seem to be from the National Instruments
block (which is good):
root@ni-e31x-30D280A:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:80:2F:25:02:37
inet addr:192.168.11.152 Bcast:192.168.11.255
I see a warning early in boot about using a MAC address from ROM. I'm
not sure where that came from.
