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 inmlx5dv_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.
