+Keep only a single connected technology at any time. When a new
+service is connected by the user or a better one is found according
+to PreferredTechnologies, the new service is kept connected and all
+the other previously connected services are disconnected. With this
+setting it does not matter whether the previously connected services
+are in 'online' or 'ready' states, the newly connected service is
+the only one that will be kept connected. A service connected by the
+user will be used until going out of network coverage. With this

+The default value is wifi,bluetooth,gadget. Only those technologies listed
+here are used for tethering. If one wants to tether ethernet,
+then add "ethernet" in the list.
+NOTE that if ethernet tethering is enabled, then a DHCP server is
+started on all ethernet interfaces. Tethered ethernet should
+never be connected to corporate or home network as it will disrupt
+normal operation of these networks. Due to this ethernet is not
+tethered by default. Do not activate ethernet tethering unless you
