overall looks good. few nits here and there...

With amount of changes to bpf core in patch 1 it definitely
needs to go via net-next, otherwise merge window conflicts
will be nasty.

Ingo, Peter, could you please review perf bits in patches 2 and 3,
so we can take the whole set via net-next.

Thanks!
