OID_ATM_GET_NEAREST_FLOW
The OID_ATM_GET_NEAREST_FLOW OID requests an ATM miniport driver to return the media parameters for a VC as close as possible to specified media parameters. The InformationBufferpassed to MiniportCoRequestcontains a CO_CALL_PARAMETERSstructure that points to a CO_MEDIA_PARAMETERSstructure. The CO_MEDIA_PARAMETERS structure specifies the target media parameters and also contains ROUND_DOWN_FLOW and ROUND_UP_FLOW flags that indicate whether the miniport driver should round the actual media parameter values up or down with respect to the specified target media parameters.
The caller of NdisCoRequestmust always specify a VC when passing this OID. If the caller fails to specify a VC, the miniport driver must return NDIS_STATUS_INVALID_DATA.
