Re: bug about MPC8260 FEC driver?


I use below command to get source tree.
    cvs -z3 -d :pserver:anoncvs at sources dot redhat dot com:/cvs/ecos co -P ecos
I think it is the lastest.

In fact, I couldn't see other version of if_fec.c in its log.

What version of the code are you referring to?  I made major
changes in how the data cache is handled in this driver a 
long time ago (back in October, 2002).

Try updating to the latest CVS and see if you still have problems.
