Bug description:
As part of programming OpenvSwitch, Neutron will add to which
protocols bridges support [0].
However, the Open vSwitch `ovs-vswitchd` process does not appear to
always update its perspective of which protocol versions it should
support for bridges:
# ovs-ofctl -O OpenFlow14 dump-flows br-int
2019-11-12T12:52:56Z|00001|vconn|WARN|unix:/var/run/openvswitch/br-int.mgmt:
version negotiation failed (we support version 0x05, peer supports version 0x01)
ovs-ofctl: br-int: failed to connect to socket (Broken pipe)
# systemctl restart ovsdb-server
# ovs-ofctl -O OpenFlow14 dump-flows br-int
cookie=0x84ead4b79da3289a, duration=1.576s, table=0, n_packets=0, n_bytes=0,
priority=65535,vlan_tci=0x0fff/0x1fff actions=drop
cookie=0x84ead4b79da3289a, duration=1.352s, table=0, n_packets=0, n_bytes=0,
priority=5,in_port="int-br-ex",dl_dst=fa:16:3f:69:2e:c6 actions=goto_table:4
...
(Success)
The restart of the `ovsdb-server` process above will make `ovs-
vswitchd` reassess its configuration.
