e1000 driver not ethtool aware...
Last modified: 2007-11-30 17:06:54 EST
Description of problem:
Ethtool does not work properly with the e1000 driver in RHEL 2.1
# uname -a
Linux homocorrectus.mine.nu 2.4.9-e.49smp #1 SMP Fri Aug 6 11:44:58

# ethtool eth2

eth2: negotiated 100baseTx-FD flow-control, link ok
So this is very bad for folks who need gigabit support for their NIC
A work around is to use the e1000_5220k1 for the interface instead,
which works correctly with ethtool.
