[ovs-dev] [PATCH v2 0/6] userspace: Packet type-aware pipeline

[Zoltán Balogh]

This patch set is the 2nd part of an initiative presented by Jan Scheurich: 
https://mail.openvswitch.org/pipermail/ovs-dev/2017-May/332367.html

It takes the patch set referred by the link above as a bases.

The goal is to deal with non-Ethernet packets in OVS for advanced use cases 
like L3 tunneling or NSH. The initiative is centering on the new OpenFlow 
concepts of "Packet type-aware pipeline" (PTAP) and "Generic encap/decap 
actions" (EXT-382). The overall design is documented in:
https://docs.google.com/document/d/1oWMYUH8sjZJzWa72o2q9kU0N6pNE-rwZcLH3-kbbDR8

These patches introduce the OXM field MFF_PACKET_TYPE, the 'packet-type-aware' 
bridge property, add support for versatile tunnel ports, provide new unit 
tests, implement packet-in for non-Ethernet packets and introduce OF 1.5 
packet-out handling.

The present series v2 supersedes v1 (https://mail.openvswitch.org/pipermail/ovs-dev/2017-April/331023.html), 
V2 was rebased to v6 of "userspace: Support for L3 tunneling" patch series 
mentioned before. It fixes warnings and some of its patches were merged 
together.

 userspace: Add OXM field MFF_PACKET_TYPE
 userspace: Add bridge property 'packet-type-aware'
 userspace: Handling of versatile tunnel ports
 tests: Added unit tests in packet-type-aware.at
 userspace: Complete Packet In handling
 userspace: Introduce OF 1.5 packet-out

Changes v1 -> v2:
* Rebased to v6 of "userspace: Support for L3 tunneling" patch series
* Fixed warnings
