No. Then we end up requiring ice to be loaded even when just want to use irdma 
with x722 [whose ethernet driver is "i40e"].
This will not allow us to be a unified RDMA driver.

Yes, but they only have a single ethernet driver today I presume.

Here we have a single RDMA driver and 2 ethernet drivers, i40e and ice.
