NAME         top

       mlx5dv_modify_qp_sched_elem - Connect a QP with a requestor and/or
       a responder scheduling element

SYNOPSIS         top

              int mlx5dv_modify_qp_sched_elem(struct ibv_qp *qp,
                              struct mlx5dv_sched_leaf *requestor,
                              struct mlx5dv_sched_leaf *responder);

DESCRIPTION         top

       The QP scheduling element (SE) allows the association of a QP to a
       SE tree.  The SE is described in mlx5dv_sched_node_create(3) man
       page.

       By default, all QPs are not associated to SE.  The default setting
       is ensuring fair bandwidth allocation with no maximum bandwidth
       limiting.

       A QP can be associate to a requestor and/or a responder SE
       following the IB spec definition.

RETURN VALUE         top

       upon success 0 is returned or the value of errno on a failure.
