[ovs-dev] [PATCH 0/6 v2.6] Basic MPLS actions and matches

[Simon Horman]

Hi,

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

The main limitation of this implementation is that it only
supports manipulating the outer-most MPLS label.

Key difference between the previous post, v2.5:

* Dropped "flow: Set ttl in flow_compose()", this is
  now present in the master branch

* Dropped "nx-match: Do not check pre-requisites for load actions",
  instead, dl_type changes are tracked to allow correct pre-requisite
  checking in the presence of push_mpls and pop_mpls actions.

Changes are details in the changelog of each patch.

The testsuite passes when this series is applied on top
of the current master branch.

Diffstat and git information is provided to aid review.
