Changes In RFC Version 7
-------------------------

0) First time removing the RFC tag!

1) Removed XDP cookie. It turns out as was pointed out by Toke(Thanks!) - that
using bpf links was sufficient to protect us from someone replacing or deleting
a eBPF program after it has been bound to a netdev.

2) Add some reviewed-bys from Vlad.

3) Small bug fixes from v6 based on testing for ebpf.

4) Added the counter extern as a sample extern. Illustrating this example because
   it is slightly complex since it is possible to invoke it directly from
   the P4TC domain (in case of direct counters) or from eBPF (indirect counters).
   It is not exactly the most efficient implementation (a reasonable counter impl
   should be per-cpu).
I think that I already shared my reservations about this series.

On top of that, please, please, please make sure that it builds cleanly
before posting.

I took the shared infra 8 hours to munch thru this series, and it threw
out all sorts of warnings. 8 hours during which I could not handle any
PR or high-prio patch :( Not your fault that builds are slow, I guess,
but if you are throwing a huge series at the list for the what-ever'th
time, it'd be great if it at least built cleanly :(

FWIW please do not post another version this week (not that I think
that you would do that, but better safe than sorry. Last week the patch
bombs pushed the shared infra 24h+ behind the list..)
