* Auto-Initialization
* -------------------
*
* If the application defines only one interface (`GNRC_NETIF_NUMOF == 1`),
* then RPL will be initialized on this interface.
*
* If the application defines several interfaces (`GNRC_NETIF_NUMOF > 1`),
* then RPL will be initialized on the interface `GNRC_RPL_DEFAULT_NETIF`.
* Your application is responsible for setting `GNRC_RPL_DEFAULT_NETIF` to a
* valid interface PID, e.g. via `CFLAGS`.
*
* Initializing RPL on multiple interfaces automatically is currently not supported.
* Call `gnrc_rpl_init()` manually from your application for the desired interfaces in this case.
*
