Hi,

I have been trying to get the speed (operating / max) of
network interfaces present in a system programmatically

The only ioctls that seem to give me this data seems to be
        SIOCGMIIPHY &
        SIOCETHTOOL

However MII has a max reporting limit of 100 mbps and ETH
seemd to have a max of 1 Gig.

Ami correct so far ?

If so, how does one find speeds of cards operating above
1 Gig, apart from scanning dmesg logs ?

And why is it that, MII inspite of having arrived on the
scene after ETHTOOL, support only upto 100mbps ?

thanks in advance
Arun
