    sys/netinet          ip_carp.c ip_carp.h 
  Log:
  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]
