$ mii-tool eth0: negotiated 100baseTx-FD flow-control, link ok $ ethtool eth0 | grep Speed Settings for eth0: Speed: 1000Mb/s net-tools-1.60-20 As I'm pretty sure mii-tool doesn't know about Gigabit speeds (none are mentioned in the man page), the manpage should be updated to reflect the fact that mii-tool usage is discouraged if ethtool works, and that it doesn't support Gigabit speeds.
This is what I see in manpage for mii-tool. Valid media are 100baseT4, 100baseTx-FD, 100baseTx-HD, 10baseT-FD, and 10baseT-HD. Anyway, I will mention ethtool there and that mii-tool is obsolete.
fixed in net-tools-1.60-40
