Is it possible to implement that quickly?
I was quite happy that I found a way to implement my tunnel program without 
having to parse iproute's output, or constructing netlink messages myself. 
(And I have no experience with the latter yet.)
Thus, if it is not too complex or fragile, it would be nice to get a libnl 
patch.
