net: introduce vlan_vid_[add/del] and use them instead of direct [add/kill]_vid ndo calls
This patch adds wrapper for ndo_vlan_rx_add_vid/ndo_vlan_rx_kill_vid functions. Check for NETIF_F_HW_VLAN_FILTER feature is done in this wrapper. Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
