We enable it by default when IPv6 is used without RPL.
With RPL, the neighbor cache (link-local IPv6 <-> MAC address mapping)
is fed whenever receiving DIO and DAO messages. This is always sufficient
for RPL routing, i.e. to send to the preferred parent or any child.
Link-local unicast to other neighbors may, however, not be possible if
we never receive any DIO from them. This may happen if the link from the
neighbor to us is weak, if DIO transmissions are suppressed (Trickle
timer) or if the neighbor chooses not to transmit DIOs because it is
a leaf node or for any reason. */
