NDIS_NIC_SWITCH_FREE_VF_PARAMETERS structure (ntddndis.h)

  • Artikel

The NDIS_NIC_SWITCH_FREE_VF_PARAMETERS specifies a PCI Express (PCIe) Virtual Function (VF) whose resources will be freed.

Syntax

typedef struct _NDIS_NIC_SWITCH_FREE_VF_PARAMETERS {
  NDIS_OBJECT_HEADER     Header;
  ULONG                  Flags;
  NDIS_SRIOV_FUNCTION_ID VFId;
} NDIS_NIC_SWITCH_FREE_VF_PARAMETERS, *PNDIS_NIC_SWITCH_FREE_VF_PARAMETERS;

Members

Header

The type, revision, and size of the NDIS_NIC_SWITCH_FREE_VF_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_NIC_SWITCH_FREE_VF_PARAMETERS structure, the driver must set the Revision member of Header to the following value:

NDIS_NIC_SWITCH_FREE_VF_PARAMETERS_REVISION_1

Original version for NDIS 6.30.

Set the Size member to NDIS_SIZEOF_NIC_SWITCH_FREE_VF_PARAMETERS_REVISION_1.

Flags

A ULONG value that contains a bitwise OR of flags. This member is reserved for NDIS.

VFId

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

Note  Resources for the VF with the specified NDIS_SRIOV_FUNCTION_ID value must have previously been allocated through an OID method request of OID_NIC_SWITCH_ALLOCATE_VF.
 

Remarks

The NDIS_NIC_SWITCH_FREE_VF_PARAMETERS structure is used in OID set requests of OID_NIC_SWITCH_FREE_VF.
