Ah! Yes, if you're running ethtool 1.8, then this was an issue (or
rather, an annoyance) in e1000.c where we would default to mac_type =
e1000_undefined for any newer hardware. Continuous updates to this file
for every piece of hardware we released got old pretty quick. We've
since changed the default mac_type to e1000_82543, which has a basic set
of registers that haven't changed with each hardware release. And
although the e1000_82546 mac_type exists, it isn't yet being assigned to
the 82546GB hardware (again, see e1000.c), thus the error.
Long story short, an updated ethtool should do the trick.
Thanks,
