* CFLAGS += -DGNRC_RPL_DEFAULT_DIO_REDUNDANCY_CONSTANT=10
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* - Make reception of DODAG_CONF optional when joining a DODAG.
* This will use the default trickle parameters until a
* DODAG_CONF is received from the parent. The DODAG_CONF is
* requested once from the parent while joining the DODAG.
* The standard behaviour is to request a DODAG_CONF and join
* only a DODAG once a DODAG_CONF is received.
