bridge: Don't insert unnecessary local fdb entry on changing mac address
[ Upstream commit 0b148def403153a4d1565f1640356cb78ce5109f ] The missing br_vlan_should_use() test caused creation of an unneeded local fdb entry on changing mac address of a bridge device when there is a vlan which is configured on a bridge port but not on the bridge device. Fixes: 2594e9064a57 ("bridge: vlan: add per-vlan struct and move to rhashtables") Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Acked-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.
