[tulip] Forcing link speeds in tulip 0.9.15-pre1 (May 12, 2001) fails for ZYNX ZX346Q.

[Ben Greear]

System: RH 7.1
Kernel 2.4.5-pre3
NICS: 1 ZX346Q quad-port
      2 EEPRO cards, single port
Tulip driver: 0.9.15-pre1 (May 12, 2001)


I'm trying to get my GUI to set the link speeds of
ethernet drivers supporting the MII-diag interface.

The eepro driver seems to be working fine for me, but
the tulip fails.  (This tulip driver also fails to
negotiate correctly and ends up with massive carrier errors, but
that is another sordid tale...)

What I am trying to do is set the link speed (to 10bt-HD, for instance),
by writing the reg0_val (in mii-diag.c parlance).

As far as I can tell from logging, that is the only configuration
write I am doing.

mii-diag seems to fail too:

[root@lf1 /root]# mii-diag -F 10bt-HD eth3
Setting the speed to "fixed", Control register 2100.
Basic registers of MII PHY #32:  1000 786c 0000 0000 01e1 41e1 0000 0000.
 Basic mode control register 0x1000: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 41e1: 100baseTx-FD 100baseTx 10baseT-FD 10baseT.
