OID_PM_REMOVE_PROTOCOL_OFFLOAD

As a set request, NDIS and protocol drivers use the OID_PM_REMOVE_PROTOCOL_OFFLOAD OID to remove a power management protocol offload from a network adapter. The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to a ULONG protocol offload identifier.

Remarks

NDIS and protocol drivers use the OID_PM_REMOVE_PROTOCOL_OFFLOAD OID to remove a protocol offload from the underlying network adapter.

The DATA.SET_INFORMATION.InformationBuffer member of the NDIS_OID_REQUEST structure must point to a ULONG value for a previously added protocol offload identifier. NDIS sets this protocol offload identifier in the ProtocolOffloadId member of the NDIS_PM_PROTOCOL_OFFLOAD structure when NDIS sent the prior OID_PM_ADD_PROTOCOL_OFFLOAD OID request to the underlying network adapter.

Remarks for miniport driver writers

NDIS ensures that the buffer size is at least sizeof(ULONG) and contains a valid protocol offload ID. Therefore, a miniport driver's MiniportOidRequest function should return NDIS_STATUS_SUCCESS for this request.

Note  If the miniport driver is resetting, its MiniportOidRequest function should return NDIS_STATUS_NOT_ACCEPTED.

Return status codes

NDIS returns one of the following status codes for this request:

NDIS_STATUS_SUCCESS

The protocol offload was removed successfully.

NDIS_STATUS_PENDING

The request is pending completion. NDIS will pass the final status code and results to the OID request completion handler of the caller after the request is complete.

NDIS_STATUS_INVALID_LENGTH

The information buffer is too small. NDIS sets the DATA.SET_INFORMATION.BytesNeeded member in the NDIS_OID_REQUEST structure to the minimum buffer size that is required, in bytes.

NDIS_STATUS_FILE_NOT_FOUND

The protocol offload identifier in the OID request is not valid.

Requirements

Version

Supported in NDIS 6.20 and later. Mandatory for miniport drivers.
