commit 039673c2a412282eba9c26f9ff4ac148748ebfb4 Author: Thomas Morin <thomas.mo...@orange.com> Date: Mon Sep 19 09:39:57 2016 +0200 OVS agent: configure both OF10 and OF13 This change avoids issues where a piece of code restricts a bridge to OF13 while there is code still needing OF10, and vice-versa, by configuring bridge to both versions. This is aimed to be a less complex and easier to merge fix than Id5ac7e6431c97fc70d8404b16f89533b6f270eee.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1622644 Title: OVS agent ryu/native implementation breaks non-OF1.3 uses Status in networking-bgpvpn: Confirmed Status in BaGPipe: New Status in neutron: Fix Released Bug description: The ryu-based OVS agent variant forces the bridge Openflow version to 1.3 only [1], which breaks a few things: - troubleshooting tools relying on ovs-ofctl, unless they specify "-O Openflow13", will break: version negotiation failed (we support version 0x01, peer supports version 0x04) ovs-ofctl: br-tun: failed to connect to socket (Broken pipe) - calling add_flow on an OVSCookieBridge derived from a bridge that is an native.ovs_bridge.OVSAgentBridge, will fail with the same error, because add_flow will call ovs-ofctl without specifying "-O Openflow13" (this issue is currently hitting networking-bgpvpn: [2]) It seems like a possible fix would be to not restrict the set of Openflow versions supported by the bridge to Openflow13, but to just *add* Openflow13 to the set of supported versions.
