/VLAN_DEVICE=device-name
       /NOVLAN_DEVICE

    Specifies the physical LAN device that is to host the VLAN
    device. The /NOVLAN_DEVICE qualifier requests deactivation of
    the VLAN device.

    When deactivating the VLAN device, the device-name is not
    required because the VLAN driver knows which device is hosting
    the VLAN device.

    Note that a VLAN device cannot be deactivated if any applications
    continue to use the device.
