Flow group size is calculated as follow: group_size = table_size / (#group_types + 1) Fixes: 038d2ef87572 ('IB/mlx5: Add flow steering support') Signed-off-by: Maor Gottlieb Signed-off-by: Leon Romanovsky --- drivers/infiniband/hw/mlx5/main.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/infiniband/hw/mlx5/main.c b/drivers/infiniband/hw/mlx5/main.c index 1bef4f5da31c..ca2cb2861afc 100644 --- a/drivers/infiniband/hw/mlx5/main.c +++ b/drivers/infiniband/hw/mlx5/main.c @@ -2038,8 +2038,8 @@ enum flow_table_type { MLX5_IB_FT_TX }; -#define MLX5_FS_MAX_TYPES 10 -#define MLX5_FS_MAX_ENTRIES 32000UL +#define MLX5_FS_MAX_TYPES 6 +#define MLX5_FS_MAX_ENTRIES BIT(16) static struct mlx5_ib_flow_prio *get_flow_table(struct mlx5_ib_dev *dev, struct ib_flow_attr *flow_attr, enum flow_table_type ft_type) -- 2.12.0 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
