Subject: [PATCH v2 net-next 0/2] 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.

Alexei Starovoitov (1):
  bpf: add bpf_redirect() helper

Daniel Borkmann (1):
  cls_bpf: introduce integrated actions
