SubjectTulip problem in Kernel 2.4.11
Date
Hello there is a definate problem with the tulip drivers in the 2.4.11
kernel.
I have a DEC DC 21041 NIC which uses the tulip drivers. I use the 2.2.19
kernel and there are
two different sets of tulip drivers listed in that kernel which I can choose
from in the 2.4.11 kernel there is only one. When I do a modprobe tulip the
driver loads fine as you can see bellow there are no strange error messages
ect. But I can not communicate though this one NIC. When I use the 2.2.19
Kernel it works fine.

I even tried copying the .config file over from the 2.2.19 to the 2.4.11 to
ensure that they would be the same options.

It works fine with the 2.2.19 Kernel but with the 2.4.11 the driver is not
functioning correctly.

I am hoping that you guys can figure out as to what is happening in the
2.4.11 kernel because it is very broken for this kernel. It is not working
what so ever. I know in the 2.2.19 there are 3 different choices for the DEC
card 2 of which make the tulip.o in the 2.4.11 there is only 1 and this one
is not working with this card. It is not communicating properly with this
NIC. All I get are time outs and not being able to connect to the DHCP
server. When I use the 2.2.19 Kernel it works fine. I pull an IP address
no problem. It is NOT an option that I have selected either in the 2.4.11
because they are the same config file.

Also in the read me it says that there was a few other people here that do
some kernel hacking so I am sending you this email as well to see what you
think about this.

This is a definate tulip driver problem that I am having here if you guys
could look at this I would greatly appreciate it.



Thanks,
