When a user explicitly requests VLAN filtering with something like:
# echo 1 > /sys/class/net/<bridge>/bridge/vlan_filtering
Switchdev propagates a SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING port
attribute.
Add support for it in the DSA layer with a new port_vlan_filtering
function to let drivers toggle 802.1Q filtering on user demand.
