Members

Header

The type, revision, and size of the NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure. This member is formatted as an NDIS_OBJECT_HEADER structure.

The miniport driver must set the members of Header to the following values:

Type

This member must be set to NDIS_OBJECT_TYPE_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES.

Revision

For the Windows Vista or Windows Server 2008 operating systems, this member must be set to NDIS_MINIPORT_ADAPTER_802_11_ATTRIBUTES_REVISION_1.

For later versions of the Windows operating systems, this member must be set to NDIS_MINIPORT_ADAPTER_802_11_ATTRIBUTES_REVISION_2.

Size

For the Windows Vista or Windows Server 2008 operating systems, this member must be set to NDIS_SIZEOF_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES_REVISION_1.

For later versions of the Windows operating systems, this member must be set to NDIS_SIZEOF_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES_REVISION_2.

For more information about these members, see NDIS_OBJECT_HEADER.

OpModeCapability

A bitmask of the miniport driver's supported operation modes. This bitmask is defined through the following:

DOT11_OPERATION_MODE_EXTENSIBLE_AP

Specifies that the miniport driver supports the Extensible Access Point (ExtAP) operation mode.

This value is available beginning with Windows 7.

DOT11_OPERATION_MODE_EXTENSIBLE_STATION

Specifies that the miniport driver supports the Extensible Station (ExtSTA) operation mode.

DOT11_OPERATION_MODE_NETWORK_MONITOR

Specifies that the miniport driver supports the Network Monitor (NetMon) operation mode.

For more information about operation modes, see Native 802.11 Operation Modes.

NumOfTXBuffers

The maximum number of media access control (MAC) service data unit (MSDU) packets that the 802.11 station can hold in its transmit queue. The miniport driver must support a minimum transmit queue depth of 64.

The value of this member must not include the number of transmit buffers that the 802.11 station uses to send packets on its own, such as Beacon packets or 802.11 control packets.

NumOfRXBuffers

The maximum number of MSDU packets that the 802.11 station can buffer in its receive queue. The miniport driver must support a minimum receive queue depth of 64.

MultiDomainCapabilityImplemented

A Boolean value that, if TRUE, specifies that the 802.11 station can operate in multiple regulatory domains. For more information about 802.11 regulatory domains, refer to the IEEE 802.11d-2001 standard.

NumSupportedPhys

The number of PHYs on the 802.11 station.

SupportedPhyAttributes

A pointer to an array of DOT11_PHY_ATTRIBUTES structures. This array must have NumSupportedPhys entries and must be sorted in the same order as the list of PHY types returned through a query of OID_DOT11_SUPPORTED_PHY_TYPES.

ExtSTAAttributes

A pointer to a DOT11_EXTSTA_ATTRIBUTES structure that specifies the attributes of the miniport driver and 802.11 station when operating in Extensible Station (ExtSTA) mode. For more information about this operation mode, see Extensible Station Operation Mode.

VWiFiAttributes

A pointer to a DOT11_VWIFI_ATTRIBUTES structure that specifies the attributes of the miniport driver and 802.11 station when it operates in Virtual WiFi mode.

This member is available beginning with Windows 7.

ExtAPAttributes

A pointer to a DOT11_EXTAP_ATTRIBUTES structure that specifies the attributes of the miniport driver and 802.11 station when it operates in Extensible Access Point (ExtAP) mode.

This member is available beginning with Windows 7.

WFDAttributes

A pointer to a DOT11_WFD_ATTRIBUTES structure that specifies the attributes of the miniport driver and 802.11 station when it operates in Wi-Fi Direct (WFD) mode.

This member is available beginning with Windows 8.

Remarks

When its MiniportInitializeEx function is called, the miniport driver must call the NdisMSetMiniportAttributes function to define the Native 802.11 attributes of the driver and 802.11 station. The miniport driver must follow these guidelines when it makes the call to NdisMSetMiniportAttributes:

  • The MiniportAttributes parameter must be set to the address of a driver-allocated block of memory that contains an NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure along with the ExtSTA attributes and an array of PHY attributes.

  • The SupportedPhyAttributes member must be the address of the array of DOT11_PHY_ATTRIBUTES structures. This array must be within the driver-allocated memory block referenced by the MiniportAttributes parameter.

  • The ExtSTAAttributes member must be the address of a DOT11_EXTSTA_ATTRIBUTES structure. This structure must be within the driver-allocated memory block referenced by the MiniportAttributes parameter.

For more information about the initialization requirements for a Native 802.11 miniport driver, see Native 802.11 Miniport Driver Initialization.
