I got the patch from http://marc.info/?l=linux-netdev&m=119756785219214 (Which didn't make it into -rc7; please fix!) and am recompiling now. Actually, I grabbed the hardware mitigation followon patch while I was at it. I notice that the comment explaining the format of CSR11 and what 0x80F10000 means got lost; perhaps it would be nice to resurrect it? 0x80F10000 80000000 = Cycle size (timer control) 78000000 = TX timer in 16 * Cycle size 07000000 = No. pkts before Int. (0 = interrupt per packet) 00F00000 = Rx timer in Cycle size 000E0000 = No. pkts before Int. 00010000 = Continues mode (CM) (Boy, that tulip driver could use a whitespace overhaul.)
