This is a bit of a hypothetical discussion of course, but I can imagine a lot 
of users with 100mbit switches in their homes (imagine all the DSL/cable 
routers out there...) that want to stop their nic from attempting to negotiate 
1000mbit.

Another scenario: forcing the NIC to negotiate only full-duplex speeds. Not 
only fun if you try it against a hub, but possibly useful.

For us it's much more interesting because we try every damn impossible 
configuration anyway and see what gives (or breaks).

Anyway, a patch to make ethtool do this was merged as Jeff Kirsher pointed out, 
so you can do this now with ethool too.

Cheers,

Auke
