The whole reason the queues are per-cpu is so that we do not
have to touch remote processor state nor use locks of any
kind whatsoever.

With multi-queue networking cards becoming more and more
available, which will split up the packet workload in
hardware across all available cpus, there is less and less
reason to make a patch like this one.

We've known about this issue for ages, and if we felt it
was appropriate to make this change, we would have done
so years ago.
