Upstream implementation: https://github.com/systemd/systemd/commit/4887b656c22af059d4e833de7b56544f24951184 [msekleta: backport of this functionality to Fedora 25 was directly requested by Jiri Pirko (he sent me an email). My guess is that no one in Fedora community will notice, but having this backported will help Mellanox engineers to test on Fedora]
