When a frame arrives on a port or transmitted by the bridge, if we have VLANs configured, validate that a given VLAN is allowed to enter the bridge.

Vlad Yasevich	243a2e63f5	bridge: Add vlan filtering infrastructure ... Adds an optional infrustructure component to bridge that would allow native vlan filtering in the bridge. Each bridge port (as well as the bridge device) now get a VLAN bitmap. Each bit in the bitmap is associated with a vlan id. This way if the bit corresponding to the vid is set in the bitmap that the packet with vid is allowed to enter and exit the port. Write access the bitmap is protected by RTNL and read access protected by RCU. Vlan functionality is disabled by default. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S.
