89K : 21143 no success report

Mon Aug 10 19:14:37 1998

Greetings,

	This is with the same 21143/QS6611 combination NIC's I've been
having such problems with.  Synopsis: default media type now via MII, no
link beat ever detected at any signal rate.  Worked with 89I and a few
other drivers (de4x5.c and win98).  Here is the debugging information:

tulip-diag:

This was with both 10base and 100base connections.  The latter two "then
0000"'s were 100base.
