Merge branch 'bpf_avoid_clone'
Alexei Starovoitov says:
====================
bpf: performance improvements
v1->v2: dropped redundant iff_up check in patch 2
At plumbers we discussed different options on how to get rid of skb_clone
from bpf_clone_redirect(), the patch 2 implements the best option.
Patch 1 adds 'integrated exts' to cls_bpf to improve performance by
combining simple actions into bpf classifier.
====================
