Did you try a cross-over cable? Actually, you shouldn't even need a
cross-over cable for gigabit devices, they should auto-select MDI vs. MDIX.
Also, I recall reading something about problems with onboard tx cksum errors
on em devices recently; you may want to turn off the tx cksum feature in
your testing. Or search the archives for txcsum or something like that.
