Subject: [PATCH net-next 0/2] bpf: introduce bpf_skb_vlan_push/pop() helpers

Let eBPF programs call skb_vlan_push/pop via helpers.
JIT changes to accomodate of re-caching of skb->data and headerlen
turned out to be pretty simple.

This patch is on top of Daniel's bpf_get_cgroup_classid():
http://patchwork.ozlabs.org/patch/495826/
to avoid merge conflicts.

Alexei Starovoitov (2):
  bpf: introduce bpf_skb_vlan_push/pop() helpers
  test_bpf: add bpf_skb_vlan_push/pop() tests
