Request for Tulip 2.2.x testing...

[-- Attachment #1: Type: text/plain, Size: 546 bytes --]

Hi all!

I was wondering if I could find anyone on here with a Tulip 21041 chip
that could do some simple testing under 2.2.15-pre15?

Questions for which answers are sought:

Does tulip.c work with your 21041 chip unmodified?
If yes, does the below patch break the tulip driver?
If no, does the below patch get your 21041 working again?

Thanks!

	Jeff

HI,

I did some testing with both versions. They both work for me in the same
way. The only difference I can see is one more line in /var/log/messages
when I start the patched module. The unpatched one gives me

kernel: tulip.c:v0.91g-ppc 7/16/99 becker@cesdis.gsfc.nasa.gov
kernel: eth0: Digital DC21041 Tulip rev 33 at 0x400, 00:00:C5:47:6A:7C,
IRQ 25.
kernel: eth0: 21041 Media table, default media 0800 (Autosense).
kernel: eth0:  21041 media #0, 10baseT.
kernel: eth0:  21041 media #4, 10baseT-FD.

The patched one gives an additional line

kernel: eth0: 21143 10baseT link beat good.

Otherwise I see no difference in performance between the two (nor with
the de4x5 driver which I am normally using).

Do you need more information?
