This is slightly different to the other switches - the VLAN table (VTU) programs in the vlan port mapping /and/ the port config (tagged, untagged, passthrough, any.) So: * Add VTU operations to program the VTU (vlan table) * abstract out the mirror-disable function so it's .. well, a function. * setup the port to have a dot1q configuration for dot1q - the port security is VLAN (not per-port VLAN) and requires an entry in the VLAN table; * add set_dot1q / get_dot1q to program the VLAN table; * since the tagged/untagged ports are now programmed into the VTU, rather than global - plumb the ports /and/ untagged ports bitmaps through the arswitch API. Tested: * AP135 - QCA9558 SoC + AR8327N switch
