From b25bd37c859f32e50a436ab9d2078b76e433008e Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Sun, 6 Aug 2023 14:01:10 +0300 Subject: net/mlx5: Move TISes from priv to mdev HW resources The transport interface send (TIS) object is responsible for performing all transport related operations of the transmit side. Messages from Send Queues get segmented and transmitted by the TIS including all transport required implications, e.g. in the case of large send offload, the TIS is responsible for the segmentation. These are stateless objects and can be used by multiple netdevs (e.g. representors) who share the same core device. Providing the TISes as a service from the core layer to the netdev layer reduces the number of replecated TIS objects (in case of multiple netdevs), and will ease the transition to netdev with multiple mdevs. Signed-off-by: Tariq Toukan Reviewed-by: Gal Pressman Signed-off-by: Saeed Mahameed --- include/linux/mlx5/driver.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/linux/mlx5') diff --git a/include/linux/mlx5/driver.h b/include/linux/mlx5/driver.h index 2f67cec1a898..7ee5b79ff3d6 100644 --- a/include/linux/mlx5/driver.h +++ b/include/linux/mlx5/driver.h @@ -679,6 +679,8 @@ struct mlx5e_resources { struct mlx5_td td; u32 mkey; struct mlx5_sq_bfreg bfreg; +#define MLX5_MAX_NUM_TC 8 + u32 tisn[MLX5_MAX_PORTS][MLX5_MAX_NUM_TC]; } hw_objs; struct net_device *uplink_netdev; struct mutex uplink_netdev_lock; -- cgit v1.2.3
