Title: Some OVS bridges may lack OpenFlow10 protocol Status in neutron: Fix Released Bug description: After commit https://review.opendev.org/c/openstack/neutron/+/371455 OVSAgentBridge.setup_controllers() no longer sets OpenFlow10 protocol for the bridge, instead it was moved to ovs_lib.OVSBridge.create(). However some (custom) OVS bridges could be created by nova/os-vif when plugging VM interface. For such bridges neutron does not call create(), only setup_controllers() - as a result such bridges support only OpenFlow13 and ovs-ofctl command fails: 2020-11-24T20:18:38Z|00001|vconn|WARN|unix:/var/run/openvswitch/br01711489f-fe.24081.mgmt: version negotiation failed (we support version 0x01, peer supports version 0x04) ovs-ofctl: br01711489f-fe: failed to connect to socket (Broken pipe) Fix: return setting of OpenFlow10 (along with OpenFlow13) to setup_controllers(). It's doesn't hurt even if bridge already has OpenFlow10 in supported protocols.
