switch: read and write vlan config from and to gigabit switches
This patch makes it possible to read and write the vlan config from and to recent switchs. This is based on a patch by jcharest and the Broadcom SDK. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35584 3c298f89-4303-0410-b956-a3cf2f4a3e73
