574 * IPv6 group descriptor.
575 *
576 * For every entry on an ifnet's if_multiaddrs list which represents
577 * an IP multicast group, there is one of these structures.
578 *
579 * If any source filters are present, then a node will exist in the RB-tree
580 * to permit fast lookup by source whenever an operation takes place.
581 * This permits pre-order traversal when we issue reports.
582 * Source filter trees are kept separately from the socket layer to
583 * greatly simplify locking.
584 *
585 * When MLDv2 is active, in6m_timer is the response to group query timer.
586 * The state-change timer in6m_sctimer is separate; whenever state changes
587 * for the group the state change record is generated and transmitted,
588 * and kept if retransmissions are necessary.
589 *
590 * FUTURE: in6m_link is now only used when groups are being purged
591 * on a detaching ifnet. It could be demoted to a SLIST_ENTRY, but
592 * because it is at the very start of the struct, we can't do this
593 * w/o breaking the ABI for ifmcstat.
