  Log:
  MFC:
    When a connection is being dropped due to a listen queue overflow,
    delete the cloned route that is associated with the connection.
    This does not exhaust the routing table memory when the system
    is under a SYN flood attack. The route entry is not deleted if there
    is any prior information cached in it.
