NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS structure (ntddndis.h)

  • Artikel

The NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS structure specifies the parameters for changing the power state of a network adapter's PCI Express (PCIe) Virtual Function (VF).

Syntax

typedef struct _NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS {
  NDIS_OBJECT_HEADER      Header;
  NDIS_SRIOV_FUNCTION_ID  VFId;
  NDIS_DEVICE_POWER_STATE PowerState;
  BOOLEAN                 WakeEnable;
} NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS, *PNDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS;

Members

Header

The type, revision, and size of the NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS structure. This member is formatted as an NDIS_OBJECT_HEADER structure.

The miniport driver must set the Type member of Header to NDIS_OBJECT_TYPE_DEFAULT. To specify the version of the NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS structure, the driver must set the Revision member of Header to the following value:

NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS_REVISION_1

Original version for NDIS 6.30 and later.

Set the Size member to NDIS_SIZEOF_SRIOV_SET_VF_POWER_STATE_PARAMETERS_REVISION_1.

VFId

An NDIS_SRIOV_FUNCTION_ID value that specifies the unique identifier of the VF on the network adapter.

Note  The VF with the specified NDIS_SRIOV_FUNCTION_ID value must have resources that were previously allocated through an OID set request of OID_NIC_SWITCH_ALLOCATE_VF.
 

PowerState

An NDIS_DEVICE_POWER_STATE value that specifies the power state of the network adapter.

WakeEnable

A BOOLEAN value that specifies whether the network adapter should have its WAKE# signal (on the PCI Express bus) or PME# signal (on the PCI bus) asserted as it goes into the low-power state.

Note  This value must be set to FALSE if PowerState is set to the full-power state (NdisDeviceStateD0).
 

Remarks

The NDIS_SRIOV_SET_VF_POWER_STATE_PARAMETERS structure is used in OID set requests of OID_SRIOV_SET_VF_POWER_STATE.
