The first per-vlan option added is state, it is needed for EVPN and for per-vlan STP. The state allows to control the forwarding on per-vlan basis. The vlan state is considered only if the port state is forwarding in order to avoid conflicts and be consistent. br_allowed_egress is called only when the state is forwarding, but the ingress case is a bit more complicated due to the fact that we may have the transition between port:BR_STATE_FORWARDING -> vlan:BR_STATE_LEARNING which should still allow the bridge to learn from the packet after vlan filtering and it will be dropped after that. Also to optimize the pvid state check we keep a copy in the vlan group to avoid one lookup. The state members are modified with *_ONCE() to annotate the lockless access.
