Description langod 1999-11-15 16:00:04 UTC
There is a wrong driver/module in pcitable for DEC 21142/43 network card:
Currently it is tulip but should be de4x5, here is the diff:

< 0x1011	0x0019	"tulip"	"DEC|DECchip 21142/43"
> 0x1011	0x0019	"de4x5"	"DEC|DECchip 21142/43"

if you check in /usr/src/linux/Documentation/networking/
de4x5.txt tulip.txt
you can see that de4x5 is a better choice for 21142/43 dec network cards.

Hmm... I'm not sure that that docummentation is particularly relevant; it's
more than a year out of date.

Does the de4x5 driver work for you where the tulip does not?

Comment 2 langod 1999-11-15 17:34:59 UTC
Yes, the de4x5 works for me fine.
also kudzu configured the device correctly with modified pcitable.
Regarding kernel documentation, if you search for:

grep 2114 de4x5.txt tulip.txt

de4x5.txt:	DC21140[A]
de4x5.txt:	DC21142
de4x5.txt:	DC21143
de4x5.txt:    all  cards running the dc2114x  series chips in particular.  Cards

tulip.txt:|     EtherPower 10/100 PCI(9332DST)  |21140      |Pentium/UDB  |
tulip.txt:|     EtherWorks 100/10 PCI(DE500-XA) |21140      |Pentium      |
tulip.txt:|     LA100PCI-T                      |21140      |Pentium/UDB  |
tulip.txt:|     EM110                           |21140      |Pentium      |

I think this is clear enough that tulip is not the right choice.

Comment 3 Bill Nottingham 1999-11-15 17:40:59 UTC
The tulip.txt file hasn't been updated in a year and a half -
using it as a definitive list of the cards that it supports probably isn't
a good idea.

Does the tulip driver fail in some way that the de4x5 driver works?

Comment 4 langod 1999-11-15 18:09:59 UTC
Yes the documentation files are old, but also the source code
tulip.c is much older than de4x5.c:

last change in de4x5.c:
      0.544   8-May-99    Fix for buggy SROM in Motorola embedded boards using

last change in tulip.c:
 static const char version[] = "tulip.c:v0.89H 5/23/98\n";

Why do you insist that this is not a problem?
de4x5 works tulip does not work for my card.
That's all I can say.

Comment 5 Bill Nottingham 1999-11-15 19:14:59 UTC
OK, that's the information I wanted (that the tulip did *not* work.)

Of course, it probably will work with the 0.91 driver. Fun.
Fixed in CVS, will make its way into the next kudzu release.
