This was a wholesale change done across the entire tree, they were all
straightforward transformations that didn't change what the code did.

It was a change done so that we could hide the skb data buffering
details to the point where we could change the protocol header
pointers into 32-bit offsets which saves 4 bytes per such pointer per
protocol header stored in struct sk_buff.

We're not going to notify the maintainer of each of the hundreds of
source files we had to touch in order to pull this off, sorry.

These changes were posted to [email protected], they also
sat in Andrew Morton's -mm tree for quite some time.
