ar71xx: Fix tagged+untagged operation on AR8327N (#12181)
Replace the global "vlan_tagged" variable with an array storing the tagging state per vlan. The code was taken from #12181, tested and cleaned up by Saverio Proto with additional bug fixes supplied by Álvaro Fernández. Tested-by: Jo-Philipp Wich <jow@openwrt.org> Signed-off-by: Saverio Proto <zioproto@gmail.com> Signed-off-by: Álvaro Fernández <noltari@gmail.com> SVN-Revision: 40777
