Problem with full duplex or MII with DEC 21143
Sat Oct 31 07:13:00 1998
I have a pair of DEC 21143 cards connected via a null modem
cable. These work fine at 100baseTX, except that I can't
get full duplex to enable. I can set options=14, in which
case full duplex is reported by tulip-diag, but then the
cards will not communicate. I have tried a variety of options,
(including no options) and a variety of driver versions (0.88 0.89L 0.90
etc) all to no avail. Any ideas?
A related problem may be that MII appears not to be recognized.

eth1: Index #3 - Media 100baseTx-FD (#5) described by a 21143 SYM PHY (4)
and that's all. On the mailing list archive someone showed another line
concerning MII, that I do not appear to have.
These were $15 cards, so perhaps I am paying for this now....
The card is CNET CN100TX, it advertises full duplex capability.
