In order to reach to 100Gbps with 64B traffic, it is\nneeded to further save PCIe bandwidth by increasing the number of strides\nin a WQE. It is now 64 by default but adjustable by a PMD parameter -\nmprq_log_stride_num.\n\nSigned-off-by: Yongseok Koh <yskoh@mellanox.com>\nAcked-by: Shahaf Shuler <shahafs@mellanox.com>\n---\n drivers/net/mlx5/mlx5_defs.h | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)",
