[olsr-dev] Why are 1-hop routes with destination==gateway added

Hi all,

I have a small (maybe stupid) question.

In the function olsr_add_routes_in_kernel, there is special code that adds 1-hop routes to destinations, the gateway being the
destination itself. These routes are consequently added first (and deleted last in the function olsr_delete_routes_from_kernel).

My question is: why are these routes added at all? Since these are 1-hop neighbors, these destinations would have been reached
anyway, because the network routes to all connected networks are already in the routing table by default.
