In that case both relaxed ordering read and write are activated. This commit will optimize the usage of relaxed ordering by enabling it when the read OR write features are supported. Each relaxed ordering type will be activated according to its own capability bit. This will align the DevX flow with the verbs implementation of ibv_reg_mr when using the flag IBV_ACCESS_RELAXED_ORDERING Fixes: 53ac93f71ad1 ("net/mlx5: create relaxed ordering memory regions") Cc: stable@dpdk.org Signed-off-by: Tal Shnaiderman Acked-by: Matan Azrad --- drivers/common/mlx5/mlx5_devx_cmds.c | 8 ++++---- drivers/common/mlx5/mlx5_devx_cmds.h | 3 ++- drivers/net/mlx5/linux/mlx5_os.c | 13 +++++++++---- drivers/net/mlx5/mlx5.h | 3 ++- drivers/net/mlx5/mlx5_flow.c | 3 ++- drivers/vdpa/mlx5/mlx5_vdpa_lm.c | 3 ++- drivers/vdpa/mlx5/mlx5_vdpa_mem.c | 3 ++- 7 files changed, 23 insertions(+), 13 deletions(-) diff --git a/drivers/common/mlx5/mlx5_devx_cmds.c b/drivers/common/mlx5/mlx5_devx_cmds.c index 8aee12d527..27eff5f313 100644 --- a/drivers/common/mlx5/mlx5_devx_cmds.c +++ b/drivers/common/mlx5/mlx5_devx_cmds.c @@ -267,10 +267,10 @@ mlx5_devx_cmd_mkey_create(void *ctx, MLX5_SET(mkc, mkc, pd, attr->pd);
