NAME

       mlx5dv_create_steering_anchor - Creates a steering anchor

       mlx5dv_destroy_steering_anchor - Destroys a steering anchor

SYNOPSIS

              #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

       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

   context
       The device context to associate the steering anchor with.

   attr
       Anchor attributes specify the priority and flow table type to which the anchor will point.

              struct mlx5dv_steering_anchor_attr {
                      enum mlx5dv_flow_table_type ft_type;
                      uint16_t priority;
                      uint64_t comp_mask;
              };

       ft_type
              The flow table type to which the anchor will point.

       priority
              The priority inside ft_type to which the created anchor will point.

       comp_mask
              Reserved for future extension, must be 0 now.

   mlx5dv_steering_anchor
              struct mlx5dv_steering_anchor {
                  uint32_t id;
              };

       id     The flow table ID to use as the destination when creating the flow table entry.

RETURN VALUE

       mlx5dv_create_steering_anchor() returns a  pointer  to  a  new  mlx5dv_steering_anchor  on
       success.  On error NULL is returned and errno is set.

       mlx5dv_destroy_steering_anchor() returns 0 on success and errno value on error.
