This patch breaks the build badly, I don't know how it passed anyone's
build tests :(

The functions are still used in two different files.

I've applied the first 4 patches here, but really, I shouldn't have had
to bisect down to the offending patch.

ugh.

In the set I submitted was the patch to remove usage of per channel state in netvsc.
KY dropped it, because it already is in net-next. So this patch can wait until net-next is merged.
The current split tree process is a pain and causes slow development cycles
