tulip driver BROKEN in 2.4.5-pre4

tulip driver BROKEN in 2.4.5-pre4

[J Brook]

Okay, so Jeff Garzik already knows about this - I told him last week -
but seeing as how the code has made it to a Linus pre-release without
a fix I thought I'd better post the breakage description to l-k!

The symptoms are:
In 2.4.5-pre4 (and 2.4.4-ac8 and above - note: I didn't try -ac7)
system boots up normally, card is recognised etc, but all networking
services fail because it's not possible to talk to the network. The
system appears to be stable apart from the bug (possible to compile
kernels, run X, etc.), but nothing gets to or from the network.

I'm using the "DECchip Tulip (dc21x4x) PCI support" option to get the
driver for the PCI card which has a Digital 21041 chip in it.

FWIW I think it might be related to the selection of full- or
half-duplex. 2.4.4-ac6 (which works fine) says:
  Port selection is half-duplex
when I run tulip-diag, whereas 2.4.5-pre4 says
  Port selection is full-duplex

My system is RH7.1 (using gcc-2.96 not kgcc)
Duron 750, KT133 chipset (not kt133a!)

Network card details (it is a PCI):
Kingston KNE40BT (1995)
  Digital 21041-AA  DC1017BA
  21-40756-01  Dec 1994
  S15313-02
  A 9615

 More details on request. And I'm willing to test patches...

Could you post the output of

#tulip-diag -mm -aa -f

with the broken driver?
Some code that's required for Linksys Tulip clones was moved from pnic
specific part into the generic part, perhaps that causes problems.

Here is the output from the kernels I've tested to try to get the
driver working:

 Let me know if I can provide any more useful information about the

Try drivers from http://sourceforge.net/projects/tulip/
1.1.6 drivers + 2.4.5-pre1 works OK on high load router ( one four-ports
card and one two-ports carts).
Tulip drivers from 2.4.5-pre1 are realy borken. :(

i have a 21041 dec tulip which has failed to work with
linux-2.4.5-pre[3-5] kernel drivers.  (it also fails with the
sourceforge devel version tulip-1.1.7)

it appears that the card gets lodged in full duplex mode.  however,
this could just be a superficial syndrome.

anyhow, here is the output of tulip-diag -mm -aa -f from the *broken*
driver
