Eli Cohen 3e8d61faea vdpa/mlx5: Fix MQ to support non power of two num queues ... [ Upstream commit a43ae8057c ] RQT objects require that a power of two value be configured for both rqt_max_size and rqt_actual size. For create_rqt, make sure to round up to the power of two the value of given by the user who created the vdpa device and given by ndev->rqt_size. The actual size is also rounded up to the power of two using the current number of VQs given by ndev->cur_num_vqs. Same goes with modify_rqt where we need to make sure act size is power of two based on the new number of QPs. Without this patch, attempt to create a device with non power of two QPs would result in error from firmware.
