Merge branch 'pch_gbe-Cleanups'

Paul Burton says:

====================
net: pch_gbe: Cleanups

This series begins the process of cleaning up the pch_gbe network
driver. Whilst my ultimate goal is to add support for using this driver
on the MIPS Boston development board, this series sets that aside in
favor of making some more general cleanups. My hope is that this will
both make the driver a little more maleable & reduce the probability of
me gouging out my eyes.

Applies cleanly atop net-next as of 5424ea27 ("netns: get more
entropy from net_hash_mix()").
