Public bug reported:
When multiple api and rpc workers enabled for neutron-server, sometimes
ovs agents fail to create flood flows to other ovs agents. This is
frequently reproducible when multiple api and rpc workers enabled during
migrations and also during evacuations of instances from one node to
other. Some times tunnel ports are also not created.
In these scenarios, l2pop driver is not notifying agent to create tunnel
ports and flood flows, hence agent is unable to create flood flows to
other agents.
