SubjectDavicom support in the tulip driver
As you suggested, I added/improved support for the Davicom chip to the
tulip driver. I'm going to fix the dmfe driver when I have more time.

This patch works-for-me(TM) using a Cnet card, but it would be very
interesting to see what happens with other Davicom based cards. I think it
should work, but you never know.
