    sys/netinet          ip_carp.c ip_carp.h 
  MFC (rev. 1.39 of ip_carp.c, rev. 1.2 of ip_carp.h):
    o Introduce carp_multicast_cleanup(), which removes and frees
      multicast addresses from carp interface. [1]
    o Rewrite carpdetach(), so that it does the following things: [1]
      - Stops callouts.
      - Decrements carp_suppress_preempt, if needed.
      - Downs interface and sets CARP state to INIT.
      - Calls carp_multicast_cleanup().
      - Detaches softc from carp_if and if we are the last frees
        the carp_if.
    o Use new carpdetach() in carp_clone_destroy().
    o In carp_ifdetach() acquire the carp_if lock and cleanup all
      interfaces hanging on carp_if. [1]
    o Make carp_ifdetach() static and use EVENT(9) to call it
      from if_detach(). [2]
    o In carp_setrun() exit if the softc doesn't have a valid pointer
      to parent. [1]
