From 25461ce8b3d28528f2c55f5e737e99d2906eda83 Mon Sep 17 00:00:00 2001 From: Saeed Mahameed Date: Fri, 15 Dec 2023 19:31:14 -0800 Subject: net/mlx5e: Use the correct lag ports number when creating TISes The cited commit moved the code of mlx5e_create_tises() and changed the loop to create TISes over MLX5_MAX_PORTS constant value, instead of getting the correct lag ports supported by the device, which can cause FW errors on devices with less than MLX5_MAX_PORTS ports. Change that back to mlx5e_get_num_lag_ports(mdev). Also IPoIB interfaces create there own TISes, they don't use the eth TISes, pass a flag to indicate that. This fixes the following errors that might appear in kernel log: mlx5_cmd_out_err:808:(pid 650): CREATE_TIS(0x912) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x595b5d), err(-22) mlx5e_create_mdev_resources:174:(pid 650): alloc tises failed, -22 Fixes: b25bd37c859f ("net/mlx5: Move TISes from priv to mdev HW resources") Signed-off-by: Saeed Mahameed --- include/linux/mlx5/driver.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/linux/mlx5/driver.h b/include/linux/mlx5/driver.h index 8c55ff351e5f..41f03b352401 100644 --- a/include/linux/mlx5/driver.h +++ b/include/linux/mlx5/driver.h @@ -681,6 +681,7 @@ struct mlx5e_resources { struct mlx5_sq_bfreg bfreg; #define MLX5_MAX_NUM_TC 8 u32 tisn[MLX5_MAX_PORTS][MLX5_MAX_NUM_TC]; + bool tisn_valid; } hw_objs; struct net_device *uplink_netdev; struct mutex uplink_netdev_lock; -- cgit v1.2.3 From cfbc3608a8c69b48bf238bd68f768192f0238e0d Mon Sep 17 00:00:00 2001 From: Tariq Toukan Date: Tue, 19 Dec 2023 14:46:20 +0200 Subject: net/mlx5: Fix query of sd_group field The sd_group field moved in the HW spec from the MPIR register to the vport context.
