NIC speed

[Steve]

As far as I know, mii-tool only recognizes 10/100 NIC cards. 

Its difficult to get this from the man page, but FWIW.

           To handle such devices, the MII protocol also
           allows  for establishing a link by simply detecting either a 
10baseT or
           100baseT link beat.

I  would trust ethtool.
