    ovs-fw: Handle only known trusted ports
    
    Similarly to filtered ports this patch caches so called trusted ports to
    avoid processing in case of unknown port is passed down to firewall
    driver. The cached ofport is used for removal as the cache reflects
    currently installed flows.
    
    The patch also catches exception caused by inconsistency coming from
    ovsdb.

Title:
  test_trunk_subport_lifecycle fails on subport down timeout

Status in neutron:
  Fix Released

Bug description:
  subport doesn't transition to DOWN state after trunk deletion

  
  logstash query: http://logstash.openstack.org/#dashboard/file/logstash.json?query=build_name%3Agate-tempest-dsvm-neutron-dvr-multinode-scenario-ubuntu-xenial-nv%20AND%20build_branch%3Amaster%20AND%20message%3A%5C%22Timed%20out%20waiting%20for%20subport%20%5C%22%20AND%20message%3A%5C%22to%20transition%20to%20DOWN%5C%22%20AND%20tags%3Aconsole

  The agent log is filled with trace:

  Error while processing VIF ports: OVSFWPortNotFound: Port
  526e3ca9-9af3-4b94-8550-90a5bdc9b4e7 is not managed by this agent.

  nv/e11aeaf/logs/screen-q-agt.txt.gz?level=TRACE

  Incidentally, this port is a parent of a trunk port.

  Now the trunk's OVSDB handler on the agent side relies on the OVS
  agent main loop to detect the port removal and let it notify the
  server to mark the logical port down. I wonder if these exceptions
  prevent that from happening.
