force full duplex

[Jacob Friis Larsen <jfl@list.idg.dk>]

How can I make my system run with full duplex?

In /var/log/dmesg I see:
tg3: eth1: Link is up at 100 Mbps, half duplex.
tg3: eth1: Flow control is off for TX and off for RX.
tg3: eth0: Link is up at 100 Mbps, half duplex.
tg3: eth0: Flow control is off for TX and off for RX.

Thanks,
Jacob
