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