The original 82c168 PNIC chip has built in NWAY support which is
used on certain early LinkSys LNE100TX and Matrox FastNIC cards,
however it is horribly broken and difficult to use reliably.
Consequently, autonegotiation is not currently supported for this
chipset: the driver defaults the NIC to 10baseT half duplex, and it's
up to the operator to manually select a different mode if necessary.
(Later cards use an external MII transceiver to implement NWAY
autonegotiation and work correctly.)
