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.
Differences between the previous post, v2.9, and this post, v2.10:
* Rebase
* Check the size of nx_action_mpls_ttl.
nx_action_pop_mpls was being checked
due to a cut-and-paste error
Key differences between v2.8 and v2.9
* Rebase
and fix tests accordingly
* Always update MPLS bos pointer when
VLAN pop is performed in kernel datapath.
Key differences between v2.7 and v2.8
* Rebase
Key differences between v2.6 and v2.7
* When encoding TTL actions (the last 4 patches) for
an OpenFlow 1.1+ message, encode them as OpenFlow 1.1+
actions. Previously they were encoded as NX matches.
Key differences between v2.5 and v2.6
* 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.
Key differences between v2.4 and v2.5
* Various clean-ups and fises to
"User-Space MPLS actions and matches"
as noted in its changelog.
* New patches to add support for TLS actions
* Inclusion of Justin Pettit's patch
"flow: Set ttl in flow_compose()",
which is a dependency of the
"Add support for copy_ttl_out action" patch.
Key differences between v2.3 and v2.4
* Minor cleanup to "User-Space MPLS actions and matches"
as detailed in its changelog.
* A new patch at the end of the series
"Add support for set_mpls_ttl action"
Changes are detailed 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.
