Please copy netdev@xxxxxxxxxxxxxxx on net patches.

This patch modifies a net driver as well as the networking core. These
subsytems have different maintainers who run different development trees.
Consequently I must split your patch into two and change their titles and
changelogs appropriately.

Please do this for us in future, thanks.

If we're going to do this then it would probably make sense to change
dev_alloc_skb_node() so that it takes a `struct net_device *' rather than a
bare node-id. That's a call which the net guys will need to make, which is
why we cc them on our emails.

It might help to edit code in an 80-col xterm.

Please run scritps/checkpatch.pl across all your diffs. Its suggestions
are by no means compulsory, but they do provide things for you to check up
and and have a think about, thanks.

I won't apply this (these) patches because I expect API changes.
