Hi Greg - 

The irdma driver is the virtbus driver that would bind to the virtual devices created
in this netdev driver.

It is decoupled from this series as it was deemed in a prior discussion that irdma driver
would go in a +1 cycle from net series to avoid conflicts. See discussion here --
https://lore.kernel.org/netdev/46ed855e75f9eda89118bfad9c6f7b16dd372c71.camel@intel.com/

The irdma driver is currently posted as an RFC series with its most recent submission here --
