For ease of review if there's a new version it might be as well to just
reference it anyway, hopefully the mlx5 code will be merged fairly
quickly once the bus itself is merged.  It's probably easier all round
than adding the reference later, it seems more likely that mlx5 will get
merged than that it'll fall by the wayside.
