I now have v.90z tulip driver trying to work with the SMC8432T .
I verify in /var/log/messages that indeed v.90z is loaded.
eth0: Digital DC21041 Tulip rev 33 at 0xe880, 21041 mode, .... IRQ 11

In messages time stamped after the latest boot, I continue to get the
"no 21041 10baseT link beat, Media switched to 10base2" message
followed 30 seconds later by "21041 media switched to 10baseT"
This cycle repeats again with only 10 seconds on 10base2, and continues to
do so.

The first thing logged for eth0 on this boot cycle is
"eth0:21041 Media information at 30, default media 0800 (Autosense)."

The option to force and lock on 10baseT is still not working properly.

Your assistance is appreciated.
