Add final rtnetlink constants

This is a follow up to the PR #1351 which is for issue #1059 as it was closed before I realized there's one last set of netlink constants needed for use with rtnetlink. I'm marking this as WIP until I've verified everything's good with CI and that I've included all necessary constants. I'll remove WIP once it's passing CI and it's ready for review.
