Forcing NIC to operate at Full Duplex using Ethtool

This is a follow up blog entry from Using ethtool to check and change Ethernet Card Settings

To force the NIC to use full duplex, 100Mbps, and autonegotiate off, you can
put this in /etc/sysconfig/network-scripts/ifcfg-eth0
ETHTOOL_OPTS="speed 100 duplex full autoneg off"

This is taken from ethtool from softpanorama.
