In order to improve performance, we allow user-mode drivers to use a larger page size to allocate WQE buffers, thereby reducing the latency introduced by HW page switching. User-mode drivers will be allowed to allocate WQE buffers between 4K to system page size. During ibv_create_qp(), the driver will dynamically select the appropriate page size based on ibv_qp_cap, thus reducing memory consumption while improving performance.
