I'm still having similar trouble with a 21140-based Asante card; the
code to talk to the PHY has never worked.

As I understand things, Matt Thomas's preferred method to making if_de
work correctly on all variants is work is to get ifmedia implemented
for NetBSD, and then to use a still-newer variant of his if_de driver,
which uses ifmedia on BSDI 3.0 and (I think) works with the newer
cards.

I seem to have bad luck getting in synch with Matt;  I'm unlikely to 
have an opportunity to do more hacking on ifmedia until about March 15.
