I don't think this is possible. It's the responsibility of the driver
to tweak certain registers once negotiation has been completed. I
have an internal version of the tlp driver which mostly autonegotiates
with the Macronix 98715AEC-C parts (such as used in the Sohoware
fast ethernet card). However, there are some pathological states which
it can get into, and the code is not as general as it should be.
I haven't tested full duplex since before some recent bugfixes.
Full duplex was generating too many errors when I last used it,
so I turned it off. That at least lets it work by default in most
places, since the negotiation is completed correctly.
