[PATCH net-next v22 0/3] openvswitch: add 802.1ad support

[Eric Garver <e@erig.me>]

This series adds 802.1ad support to openvswitch. It is a continuation of the
work originally started by Thomas F Herbert - hence the large rev number.

The extra VLAN is implemented by using an additional level of the
OVS_KEY_ATTR_ENCAP netlink attribute.
In OVS flow speak, this looks like

   eth_type(0x88a8),vlan(vid=100),encap(eth_type(0x8100), vlan(vid=200),
                                        encap(eth_type(0x0800), ...))

The userspace counterpart has also seen recent activity on the ovs-dev mailing
lists. There are some new 802.1ad OVS tests being added - also on the ovs-dev
list. This patch series has been tested using the most recent version of
userspace (v3) and tests (v2).

v22 changes:
  - merge patch 4 into patch 3
  - fix checkpatch.pl errors
    - Still some 80 char warnings for long string literals
  - refresh pointer after pskb_may_pull()
  - refactor vlan nlattr parsing to remove some double checks
  - introduce ovs_nla_put_vlan()
  - move triple VLAN check to after ethertype serialization
  - WARN_ON_ONCE() on triple VLAN and unexpected encap values

v21 changes:
  - Fix (and simplify) netlink attribute parsing
  - re-add handling of truncated VLAN tags
  - fix if/else dangling assignment in {push,pop}_vlan()
  - simplify parse_vlan()
