dc no worky with <Xircom X3201 10/100BaseTX>, also LOR

[Daniel Eischen]

I can't get this Xircom CardBus Ethernet II 10/100 device to work
with FreeBSD.  The probe/attach for MII always fails causing dc to
return ENXIO.  I've tried this device on two different Dells
(Inspiron 4150 and 8100) with the same result.  The same machines
are very happy with a Xircom Cardbus 10/100 w/modem however.

What do I have to do to get this to work?

Here's the probe for the X3201 which fails.  The mem addresses
and io ports chosen are the same as for the Xircom Cardbus 10/100
w/modem that works.
