Subject: [PATCH v2.35 0/6] MPLS actions and matches

Hi,

This series implements MPLS actions and matches based on work by
Ravi K, Leo Alterman, Yamahata-san and Joe Stringer.

This series provides two changes

* Provide user-space support for the VLAN/MPLS tag insertion order
  up to and including OpenFlow 1.2, and the different ordering
  specified from OpenFlow 1.3. In a nutshell the datapath always
  uses the OpenFlow 1.3 ordering, which is to always insert tags
  immediately after the L2 header, regardless of the presence of other
  tags. And ovs-vswtichd provides compatibility for the behaviour up
  to OpenFlow 1.2, which is that MPLS tags should follow VLAN tags
  if present.

* Adding basic MPLS action and match support to the kernel datapath

Differences between v2.35 and v2.34:

* Add support for the tag ordering specified up until OpenFlow 1.2 and
  the ordering specified from OpenFlow 1.3.

* Correct error in datapath patch's handling of GSO in the presence
  of MPLS and absence of VLANs.

Patch overview:

* The first 5 patches of this series are new,
  adding support for different tag ordering.
* The last patch is a revised version of the patch to add MPLS support
  to the datapath. It has been updated to use OpenFlow 1.3 tag ordering
  and resolve a GSO handling bug: both mentioned above. Its change log
  includes a history of changes.

To aid review this series is available in git at:
