The motivation of this series is to allow some sequences of actions
that include MPLS actions to be performed using recirculation.
Sequences of actions that could not previously be handled.
For example pop_mpls:0x0800,dec_ttl.
This uses recirculation after the pop_mpls action to allow access to L3
information of the inner packet which is used by the dec_ttl action.
This series begins by improving the existing recirculation infrastructure
and allowing output to bonding interfaces to work with recirculation
for packet_out messages with an in_port that is not present in the
datapath.
The series then builds on this to add recirculation for MPLS.
Key changes between v2 and v3
* Drop support for patch ports
* Rework support for packet out
- Broken out into separate patches which start by
adding infrastructure and using it for recirculation for bonding
Key changes between v1 and v2
* Support for: packet_out and patch ports
* More tests
In order for the test-suite to pass and "ofproto-dpif: MPLS recirculation"
to apply without a minor conflict the following patches are required:
[PATCH/RFC] ofproto-dpif-upcall: Filter translated mask using flow
[PATCH v3] ofproto: per-table statistics
And the following patch should be reverted
1f8675481e8cc976 "ofproto-dpif-upcall: Fix ovs-vswitchd crash."
