Below is a more generic patch to do fib_lookup via netlink. For others
we should say that we discussed this as a way to verify route selection.
It's also possible there are others uses for this.
In short the fist half of struct fib_result_nl is filled in by caller
and netlink call fills in the other half and returns it.
In case anyone is interested there is a corresponding user app to compare
the full routing table this was used to test implementation of the LC-trie.
