Subject: [PATCH 0/2 net-next] critical ingress path performance improvements

This patch improves performance of the super-critical ingress path by moving
the qdisc ingress code to sch_ingress, where this really belongs.

This patchset also removes the Qdisc->enqueue() indirection since this does not
enqueue anything.

This is roughly 92199pps, ~0.42% more performance on my old box.

As it's been stated before, most users don't need this:

24824a09 ("net: dynamic ingress_queue allocation")

So getting the code inlined into the core introduces a penalty to everyone in
this world.

Please apply, thanks!

  net: move qdisc ingress filtering code where it belongs
