net: dsa: support VLAN filtering switchdev attr
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.
