Eli Cohen 83ef73b27e vdpa/mlx5: Use write memory barrier after updating CQ index ... Make sure to put dma write memory barrier after updating CQ consumer index so the hardware knows that there are available CQE slots in the queue. Failure to do this can cause the update of the RX doorbell record to get updated before the CQ consumer index resulting in CQ overrun.
