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
?

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.

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
