I do not *G
hmm i don`t really know the bsd routing code,..
but the os-unspecific routing code has no support, for try again,..
as it does not even look at the return code of olsr_add_kernel_route(rt); =
so the os-specific code gets only one chance to do its job,.. (it might
immediately retry (or do whatever) before it returns, but that`s it,..)
one reason for this ist that it would get a bit complicated, to handle
failure on this level
as there are dependencies between route changes (e.g. routes dependencies on
already existing singlehop-route to their gateway)
