Declare Rx VLAN filtering as supported and user-changeable only when there are VLAN filtering entries available on the DPNI object. Even then, rx-vlan-filtering is by default disabled. Also, populate the .ndo_vlan_rx_add_vid() and .ndo_vlan_rx_kill_vid() callbacks for adding and removing a specific VLAN from the VLAN table.
