Good diagnostic :-)

That's bad. The transceiver doesn't receive any information about what the 
other end (the switch) is capable of. If the switch would be manageable  
I'd say that Full-Duplex was forced on it.

You could try 'mii-diag -r' or 'mii-diag -R' to see if anything changes. 
After each of them wait at least a minute before looking for the result.

So it's a problem with the driver ? Strange...
