3.13.11-ckt26 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>
commit 5ebc784625ea68a9570d1f70557e7932988cd1b4 upstream.
Since the mdb add/del code was introduced there have been 2 br_mdb_notify calls when doing br_mdb_add() resulting in 2 notifications on each add.
Example: Command: bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent Before patch: root@debian:~# bridge monitor all [MDB]dev br0 port eth1 grp 239.0.0.1 permanent [MDB]dev br0 port eth1 grp 239.0.0.1 permanent
After patch: root@debian:~# bridge monitor all [MDB]dev br0 port eth1 grp 239.0.0.1 permanent
