3.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Yasevich <vyasev...@gmail.com>
[ Upstream commit c095f248e63ada504dd90c90baae673ae10ee3fe ]
As Toshiaki Makita pointed out, the BRIDGE_INPUT_SKB_CB will
not be initialized in br_should_learn() as that function
is called only from br_handle_local_finish(). That is
an input handler for link-local ethernet traffic so it perfectly
correct to check br->vlan_enabled here.
Reported-by: Toshiaki Makita<toshiaki.maki...@gmail.com>
Fixes: 20adfa1 bridge: Check if vlan filtering is enabled only once.
