Please note that Jakub's question about self-tests still stands off.

I think the easier path for that goal is to have this patch merged, and 
than the iproute counter-part, and finally adds the related functional 
tests (you will need to probe the kernel and iproute features), but 
please follow-up on that, thanks!
