NDIS_SWITCH_PORT_PROPERTY_PROFILE structure

The NDIS_SWITCH_PORT_PROPERTY_PROFILE structure specifies a policy property for a Hyper-V extensible switch port that the extensible switch extension saves in its own policy store instead of in the Hyper-V policy store. In this case, policy definitions are identified by property profiles within the driver's policy store.

Syntax


typedef struct _NDIS_SWITCH_PORT_PROPERTY_PROFILE {
  NDIS_OBJECT_HEADER                          Header;
  ULONG                                       Flags;
  NDIS_SWITCH_PORT_PROPERTY_PROFILE_NAME      ProfileName;
  GUID                                        ProfileId;
  NDIS_VENDOR_NAME                            VendorName;
  GUID                                        VendorId;
  UINT32                                      BindingType;
  GUID                                        NetCfgInstanceId;
  struct {
    UINT32 PciSegmentNumber  :16;
    UINT32 PciBusNumber  :8;
    UINT32 PciDeviceNumber  :5;
    UINT32 PciFunctionNumber  :3;
  } PciLocation;
  UINT32                                      CdnLabelId;
  NDIS_SWITCH_PORT_PROPERTY_PROFILE_CDN_LABEL CdnLabel;
} NDIS_SWITCH_PORT_PROPERTY_PROFILE, *PNDIS_SWITCH_PORT_PROPERTY_PROFILE;

Members

Header

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

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

NDIS_SWITCH_PORT_PROPERTY_PROFILE_REVISION_1

Original version for NDIS 6.30 and later.

Set the Size member to NDIS_SIZEOF_NDIS_SWITCH_PROPERTY_PROFILE_REVISION_1.

Flags

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

ProfileName

An NDIS_SWITCH_PORT_PROPERTY_PROFILE_NAME value that specifies the user-friendly name of the profile property.

ProfileId

A GUID value that uniquely identifies the profile property.

VendorName

An NDIS_VENDOR_NAME value that specifies the user-friendly name of the vendor that defined the port profile.

VendorId

A GUID value that identifies the vendor that defined the port profile.

BindingType

A UINT32 value that contains a proprietary value that is defined by the independent software vendor (ISV).

NetCfgInstanceId

A GUID value that specifies the NetCfgInstanceId registry value of the underlying network adapter connection for which the property is applied.

The NetCfgInstanceId value is specified for the network adapter connection through an object identifier (OID) set request of OID_SWITCH_NIC_CREATE.

PciLocation

A structure that specifies the PCI location of the underlying physical network adapter that is specified by the NetCfgInstanceId member.

For more information, see the Remarks section.

PciSegmentNumber

A value that specifies the group of PCI buses on which the physical network adapter is attached.

PciBusNumber

A value that specifies the current PCI bus number on which the physical network adapter is attached.

PciDeviceNumber

A value that specifies the device number for the physical network adapter on the PCI bus.

Note  The PCI device number is also known as the PCI slot number.
PciFunctionNumber

A value that specifies the function number of a logical device on the physical network adapter.

CdnLabelId

A UINT32 value that specifies a unique identifier for the data that is contained in the CdnLabel member.

CdnLabel

An NDIS_SWITCH_PORT_PROPERTY_PROFILE_CDN_LABEL value that specifies the PCI Express (PCIe) CDN label for the location of the physical network adapter. A CDN label provides consistent device locations across similar hardware locations.

Remarks

The NDIS_SWITCH_PORT_PROPERTY_PROFILE structure is used by the extension to reference a policy property within a private policy store instead of the Hyper-V policy store. This allows the independent software vendor (ISV) to populate and manage this private policy store through private channels and interfaces. Vendors can distinguish their profiles from other vendors' profiles using the VendorName and VendorId fields.

Note  Port policy properties specified by an NDIS_SWITCH_PORT_PROPERTY_PROFILE structure are transparent to the extensible switch interface.

The NDIS_SWITCH_PORT_PROPERTY_PROFILE structure is used in the following OID set requests:

The NDIS_SWITCH_PORT_PROPERTY_PROFILE structure follows the NDIS_SWITCH_PORT_PROPERTY_PARAMETERS structure in the buffer that is associated with these OID set requests. The InformationBuffer member of the NDIS_OID_REQUEST structure contains a pointer to this buffer.

Note  The NDIS_SWITCH_PORT_PROPERTY_PROFILE_NAME and NDIS_SWITCH_PORT_PROPERTY_PROFILE_CDN_LABEL data types are type-defined by the IF_COUNTED_STRING structure. A string that is defined by this structure does not have to be null-terminated. However, the length of the string must be set in the Length member of this structure. If the string is null-terminated, the Length member must not include the terminating null character.

The PciLocation and CdnLabel members are only relevant if the property profile specifies a policy for an underlying physical network adapter that is attached to the extensible switch external network adapter. For example, if the external network adapter is bound to an extensible switch team of adapters, these members could specify policies for a single adapter from that team. For more information about the extensible switch team, see Types of Physical Network Adapter Configurations.

Requirements

Version

Supported in NDIS 6.30 and later.
