The hardware initializes itself to autonegotiation, advertising the standard
set of capabilities.

There is a reason for not explicitly setting the transceiver register by
default.
Initializing the settings, without an explicit specification of media type,
will break forward compatibility.  Vis. the addition of flow control -- if
the earlier drivers had initialized the advertised capabilities, the flow
control feature would have been disabled.
