> The RDMA block does not have its own PCI function, instead it must utilize
> the ice driver to gain access to the PCI device. Create a virtual bus for the
> RDMA driver to bind to the device data. The device data contains all of the
> relevant information that the IRDMA peer will need to access this PF's IIDC
> API callbacks.
> 
> Note the header file iidc.h is located under include/linux/net/intel as this is a
> unified header file to be used by all consumers of the IIDC interface.
