====================
bridge: multicast: temp and perm entries behaviour enhancements

Patch 01 adds a notify when a group is deleted via br_multicast_del_pg()
(on expire, on device delete or on device down).
Patch 02 changes how bridge device and bridge port delete and down/up are
handled. Until now on bridge down all groups were flushed, now only the
temp ones are (same for port), perm entries are flushed only on port or
bridge removal.
