I am running a Ebony board with linux-2.6.12-rc1 and I amd having intermittent
network problems. Having searched the archives it would seem that the driver
for the IBM EMAC is buggy ?
I have tried to patch my kernel with
http://kernel.ebsname.net/emac/4xx_napi_emac.diff
I believe this is almost a total driver re-write. Is this correct ?
After having a couple of problems applying the patch, Kconfig and
ibm_emac_core.c. I fixed up the original code and applied the patch.
On compilation the build fails with missing references to kzalloc,
which I guess I could easily fix with kmalloc and memset.
However there is also an undefined field, dcr_base, in the ocp_func_mal_data
structure. This structure appears to be defined in include/asm/ibm_ocp.h and
this file does not appear to be changed by the patch. I guess this patch is
for a later kernel.
Can anyone point me in the direction of a suitable patch for this kernel ?
Many Thanks
Simon.

I'm not sure about 2.6.12-rc1, but you can try GIT tree/patches at
http://kernel.ebshome.net.
Hint: you can assume that in addition to emac_3-2.6-28.diff, there are
also emac_3-2.6-NN.diff (NN < 28) on my website which were made for
earlier kernel versions :).
Alternatively, you can backport all relevant stuff from current 2.6 or
you can pay someone to do this for you.

Eugine,
Thanks for the reply. I am not familiar with git and I do not
have it installed on my system. I have looked for rpms and
tried to build git. It seems that I will need to make a lot of changes
to my system to get this going.
In a response from Wolfgang he lists a url which can be used to access
his git tree via a browser. I can not find these patch files on his git tree
but I was wondering if you made the files available in a similar way.
Alternatively can you mail the file to me ?
Or can you tell me if the files are somewhere on
http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git
If not I guess I will just have to get all the bits together to run
git and learn how to drive it.
Many Thanks
Simon.

I have eventually got git going. I am not familiar with it but following a
tutorial I did
git clone rsync://kernel.ebshome.net/linux-2.6-emac.git
cd linux-2.6-emac
git checkout
I then ran find looking for a patches dir and could not find one.
Could you please tell me how to locate the emac_3-2.6-NN.diff files.
Cheers
Simon
