The way I see it, is that mlx4_en covers the ethernet capabilities of
the hardware, and mlx4_ib only the infiniband part, I couldn't find
anything to the contrary saying that mlx4_ib needs to be loaded with
mlx4_en, but I also don't know anything about this hardware and could be
wrong here. Also we don't include or provide udebs for infiniband
drivers as far as I looked.

So for the installer, looks loading only mlx4_en solves the ethernet
part and suffices to be loaded alone, and about infiniband we don't need
or support that yet inside it. But would be good if someone with the
hardware or knowledge about it could confirm.
