Add VLAN tag option to Deco M9 Guest network in AP-mode
When using the Deco system in router mode, the guest network is tagged with 591 (default VLAN tag).
When switching to AP mode, the guest network isn't tagged anymore. Guest clients are getting an IP address in the private range (can't route/switch based on wifi network when there isn't a tag).
To be more flexible seperating the guest and lan networks in AP-mode, tagging of the guest network would help a lot to split both networks.
