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.
