Title:
  Nicira plugin: 500 when removing a router port desynchronized from the
  backend

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  If the logical switch port backing a neutron router interface port
  (device_owner=network:router_interface) is removed, then the port goes
  into ERROR state. However the interface remove process still tries to
  retrieve that port from the NVP backend, causing a 500 error.

  Different tracebacks can be generated according to the conditions
  which led to the switch port (or the peer router port) to be removed
  from the backend.
