Adding support for multiple radios about android-manet-manager

[jrobble]

Glad to hear you two got USB support working on your S4s. Which USB radios are you using?

Yes, right now the default wireless interface is hardcoded for each device; however, the Manet Manager does allow you to set the wireless interface to something else through the "Wireless Interface" setting. Once set, the property will be remembered after the device is rebooted. The same is true for the gateway interface setting.

Note that the Manet Manager will revert to the default wireless interface if the new interface is not detected after the device is rebooted and the Manet Manager is started.

You can load the appropriate kernel modules for your external device in DeviceConfig.loadKernelModules(). That should be invoked during the time the Manet Service is initialized.

I would tell your friend to manually select the wireless interface for the USB radio through the Manet Manager settings the first time he runs the app. and make sure the USB radio is hooked up before starting the Manet Manager app after the device is rebooted. If the USB radio is not hooked up, he will have to change the setting again.

Note that the wireless interface and gateway interface cannot be set to the same thing. The Manet Manager will automatically set the gateway interface to none if it detects a conflict.
