DOT11_WFD_ATTRIBUTES structure (windot11.h)

  • Article
Important  The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.
 
The DOT11_WFD_ATTRIBUTES structure is returned in an NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES indication. The structure defines the attributes related to Wi-Fi Direct (WFD) operation modes.

Members

Header

The type, revision, and size of the DOT11_WFD_ATTRIBUTES structure. The required settings for the members of Header are the following.

Member Setting
Type NDIS_OBJECT_TYPE_DEFAULT
Revision DOT11_WFD_ATTRIBUTES_REVISION_1
Size DOT11_SIZEOF_WFD_ATTRIBUTES_REVISION_1

uNumConcurrentGORole

The number of operational Wi-Fi Direct Group Owner (GO) roles simultaneously supported by the miniport driver. This value is the number of ports that can be simultaneously configured in DOT11_OPERATION_MODE_WFD_GROUP_OWNER operation mode. This member must be less than or equal to uNumWFDGroup in DOT11_VWIFI_COMBINATION_V3 returned by the miniport driver.

uNumConcurrentClientRole

The number of operational Wi-Fi Direct Client roles simultaneously supported by the miniport driver. This value is the number of ports that can be simultaneously configured in DOT11_OPERATION_MODE_WFD_CLIENT operation mode. This member must be less than or equal to uNumWFDGroup in DOT11_VWIFI_COMBINATION_V3 returned by the miniport driver.

WPSVersionsSupported

The Wi-Fi Protected Services (WPS) versions supported by the miniport driver. The miniport driver must be able to interpret WPS Information Elements (IEs) formatted to these supported WPS version specifications.

bServiceDiscoverySupported

If TRUE, the miniport supports sending and responding to WFD Service Discovery Queries. Otherwise, Service Discovery Queries are not supported.

bClientDiscoverabilitySupported

If TRUE, the miniport supports the WFD Client Discoverability. Otherwise, Client Discoverability is not supported.

bInfrastructureManagementSupported

If TRUE, the miniport supports management by the infrastructure network. Otherwise, infrastructure network management is not supported.

uMaxSecondaryDeviceTypeListSize

The maximum number of Secondary Device Types that can be configured on the WFD device.

DeviceAddress

The WFD Peer-to-Peer (P2P) device address. This address is used as a unique identifier to reference the P2P device.

uInterfaceAddressListCount

The number of P2P Interface Addresses supported by the WFD device. This value must be less than or equal to uNumWFDGroup in DOT11_VWIFI_COMBINATION_V3 returned by the miniport.

pInterfaceAddressList

A pointer to an array of P2P Interface Addresses supported by the WFD device.

uNumSupportedCountryOrRegionStrings

The number of country or region strings supported by the 802.11 station. To support multiple regulatory domains, as specified by the IEEE 802.11d-2001 standard, each country or region string identifies a regulatory domain supported by the 802.11 station.

pSupportedCountryOrRegionStrings

A pointer to an array of 802.11d country or region strings that are supported by the 802.11 station.

uDiscoveryFilterListSize

The maximum number of Discovery Filters supported by the WFD device for discovery operations. This must be at least 2.

The Discovery filters list that the WFD device must apply for device discovery is specified when OID_DOT11_WFD_DISCOVER_REQUEST is set.

uGORoleClientTableSize

The maximum number of associations that each WFD GO port supports simultaneously. The miniport must have at least this number of entries in its key-mapping key table.

Requirements
