Merge branch 'sh_eth-csum'
Sergei Shtylyov says:
====================
sh_eth: "intgelligent checksum" related cleanups
Here's a set of 2 patches against DaveM's 'net.git' repo, as they are based
on a couple patches merged there recently; however, the patches are destined
for 'net-next.git' (once 'net.git' gets merged there next time). I'm cleaning
up the "intelligent checksum" related code (however, the driver only disables
this feature for now, theres's no proper offload supprt yet).
