| 24 | * TODO: this does not really need to be an interface since Tethering runs in the same process |
| 25 | * as NetworkManagementService. Consider refactoring Tethering to use direct access to |
| 26 | * NetworkManagementService instead of using INetworkManagementService, and then deleting this |
| 27 | * interface. |
