I've noticed every time the interface is set to 'up,', the kernel reports that the link speed is set to 100 Mbps/Full Duplex, even when ethtool is used to set autonegotiation to 'off', half duplex, 10 Mbps. It can be tested by: ifconfig eth0 down ethtool -s eth0 autoneg off speed 10 duplex half ifconfig eth0 up Then checking 'dmesg' for the link speed.
