Thank you very much, Ben For completeness regarding mlx4, some work has been started on it : https://reviews.freebsd.org/D11560 There's a discussion : https://lists.freebsd.org/pipermail/freebsd-net/2017-June/048293.html Which continues here : https://lists.freebsd.org/pipermail/freebsd-net/2017-September/048906.html
