Subject: bridge: multicast: notify on group delete
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ef8299de7e2bf61ed24d1da699fa5ba13549d5f8;p=linux-beck.git

bridge: multicast: notify on group delete

Group notifications were not sent when a group expired or was deleted
due to bridge/port device being deleted. So add br_mdb_notify() to
br_multicast_del_pg().
