Subject: ibm emac driver update
Date: Mon, 12 Dec 2005 17:26:34 +0000	[thread overview]
Message-ID: <200512121726.34944.simon@baydel.com> (raw)

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.
