/**
 * nativenet transceiver interface
 *
 * A configurable transceiver for the native port.
 *
 * At the moment only the tap interface is supported, but more network
 * layers are intended. So the "configurable" part is a lie for now ;-)
 * The effect of calls like nativenet_set_channel depend on the
 * network layer.
