Add support for management vlan

Browse Source 
This adds support for the verification of a mangement vlan.
When enabled, then the switch's CPU will not listen to any packets
that are not tagged with the respective VLAN tag.
On the command line this is enabled by setting:
> vlan <vlan> mgmt

Setting the vlan ID of the management VLAN to 0 or 1 disables
the mangement VLAN function.
