I am not sure if Infiniband is actually needed. If I read the Connect X-4 page at nvidia [1] correctly the Cards mentioned in the Overview do not support Infiniband. Connect X-[5,6,7] seem to be the infiniband offerings by Mellanox [2].

I think I was mistaken in assuming it was Connect X-4. I was just basing it off of a HP DL160 spec file I found but apparently DL160 has the option for Connect X-5 which is what the machine needing the driver has (see here). When the machine booted with ubuntu, we saw MLX5 drivers get loaded.
