V0.90 bug

[Karl Vogel]

Hi,

I just tried V0.90 of the tulip driver and it still doesn't work out of
the box on my system. The driver that was included in Linux V2.0.32 works
without a problem (I believe this is 0.88), the later drivers all fail to
work.

I've found that the problem is somewhere in the t21142_timer() function.
If I change the tulip_tbl[] entry for "Digital DS21143 Tulip" to use the
tulip_timer() then it works without a problem.

So the problem is either in the t21142_timer() function _OR_ my netcard is
wrongly identified?! (I don't know anything about the tulip chip, so I'm
unable to fix the problem myself).


Here's some information that I've gathered:
