NAME

       mlx5dv_pp_alloc - Allocates a packet pacing entry

       mlx5dv_pp_free - Frees a packet pacing entry

SYNOPSIS

              #include <infiniband/mlx5dv.h>

              struct mlx5dv_pp *
              mlx5dv_pp_alloc(struct ibv_context *context,
                      size_t pp_context_sz,
                      const void *pp_context,
                      uint32_t flags);

              void mlx5dv_pp_free(struct mlx5dv_pp *dv_pp);

DESCRIPTION

       Create  /  free  a packet pacing entry which can be used for some device commands over the
       DEVX interface.

       The DEVX API enables direct access from the user space area to the mlx5 device driver, the
       packet  pacing  information  is  needed  for  few  commands where a packet pacing index is
       needed.

ARGUMENTS

       context
              RDMA device context to work on, need to  be  opened  with  DEVX  support  by  using
              mlx5dv_open_device().

       pp_context_sz
              Length of pp_context input buffer.

       pp_context
              Packet pacing context according to the device specification.

       flags  MLX5DV_PP_ALLOC_FLAGS_DEDICATED_INDEX: allocate a dedicated index.

   dv_pp
              struct mlx5dv_pp {
                  uint16_t index;
              };

       index  The device index to be used.

RETURN VALUE

       Upon  success  mlx5dv_pp_alloc  returns  a pointer to the created packet pacing object, on
       error NULL will be returned and errno will be set.
