Yeah, there’s no good answer here from an “automatically do the right thing” point of view. The reachable:netlink component (which is used for the TCP BTL) only works with libnl-3 because libnl-1 is a real pain to deal with if you’re trying to parse route behaviors. It will do the right thing

I apologize if this has been discussed before but I've been unable to find discussion on the topic. I recently went to build 3.1.2 on our cluster only to have the build completely fail during configure due to issues with libnl versions. Specifically I was had requested support for mellanox's
