NAME        top

       mlx5dv_create_steering_anchor - Creates a steering anchor       mlx5dv_destroy_steering_anchor - Destroys a steering anchor

SYNOPSIS        top

              #include <infiniband/mlx5dv.h>              struct mlx5dv_steering_anchor *              mlx5dv_create_steering_anchor(struct ibv_context *context,                                            struct mlx5dv_steering_anchor_attr *attr);              int mlx5dv_destroy_steering_anchor(struct mlx5dv_steering_anchor *sa);

DESCRIPTION        top

       A user can take packets into a user-configured sandbox and do       packet processing at the end of which a steering pipeline decision       is made on what to do with the packet.       A steering anchor allows the user to reinject the packet back into       the kernel for additional processing.mlx5dv_create_steering_anchor()Creates an anchor which will allow       injecting the packet back into the kernel steering pipeline.mlx5dv_destroy_steering_anchor()Destroys a steering anchor.

ARGUMENTS        top
