The driver provides completion ring or NQ doorbell offset for each MSIX entry requested by the RDMA driver. The NQ offset on 57500 chips is different than legacy chips. Set it correctly based on chip type for correctness. The RDMA driver is ignoring this field for the 57500 chips so it is not causing any problem.
