what should happen to IPv4 multicast vif when if_detach() is called
and struct ifnet is going away? also what should happen to
multicast routing table? if the kernel nukes vif by its own decision,
what happens to mrouted and friends?
currently there's no action taken on if_detach(), therefore multicast
vif has dangling pointer to nonexistent ifnet.
(same question goes to IPv6 multicast)
