What is the detection message?

There are several board designs for the '168.  It's important to know if
your board has a MII or SYM transceiver.  That's shown in the detection
message.

Also, the v0.91g-ppc driver has been modified many times.  You should try
the updated driver at

The '168 chip can do NWay and full duplex.  A MII transciever has its own
NWay implementation, and thus the on-chip NWay isn't used.
