Merge branch 'sfc-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc

Ben Hutchings says:

====================
Some fixes that should go into 3.9:

1. Fix packet corruption when using non-coherent RX DMA buffers.
2. Fix occasional watchdog misfiring when changing MTU or ring size.

These are longstanding bugs and should be fixed in stable as well, but
I'd like to review other recent fixes first and send a separate request
for stable inclusion.
