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.
