   3 dnl When a port disappears from a datapath, e.g. because an admin used
   4 dnl "ovs-dpctl del-port", the bridge code should be resilient enough to
   5 dnl notice and add it back the next time we reconfigure.  A prior version
   6 dnl of the code failed to do this, so this test guards against regression.
