  • uPMKIDCacheSize
    The maximum number of entries in the pairwise master key identifier (PMKID) cache that is supported by the 802.11 station.

    If the 802.11 station does not support a PMKID cache, the miniport driver must set this member to zero. Otherwise, the 802.11 station must support a PMKID cache size of at least three entries.

    For more information about the PMKID cache, see OID_DOT11_PMKID_LIST.

  • uMaxNumPerSTADefaultKeyTables
    The maximum number of per-station default cipher key tables supported by the 802.11 station. It is recommended that the 802.11 station support at least 32 per-station default cipher key tables.

  • bStrictlyOrderedServiceClassImplemented
    A Boolean value that, if set to TRUE, specifies that the 802.11 station supports the IEEE 802.11 StrictlyOrdered service class for media access control (MAC) service data unit (MSDU) packet delivery.

    For more information about the StrictlyOrdered service class, refer to Clause 6.1.3 of the IEEE 802.11-1999 standard.

  • ucSupportedQoSProtocolFlags
    A set of flags that specify the quality of service (QoS) protocols that the network adapter implements This member is either zero or a bitwise OR combination of the following flags:

    DOT11_QOS_PROTOCOL_FLAG_WMM

    The network adapter implements the 802.11 WMM QoS protocol.

    DOT11_QOS_PROTOCOL_FLAG_11E

    The network adapter implements the 802.11e QoS protocol.

  • bSafeModeImplemented
    The safe mode support capability of the network adapter/miniport driver combination. The operating system interprets this member differently depending on the value of Header.Revision:

    Revision = DOT11_EXTSTA_ATTRIBUTES_REVISION_1

    The operating system interprets the bSafeModeImplemented member as a Boolean value. If this value is TRUE, the network adapter implements the 802.11 safe mode of operation. Otherwise, the value is FALSE.

    Revision = DOT11_EXTSTA_ATTRIBUTES_REVISION_2

    The operating system interprets the bSafeModeImplemented member as a bit field that has the following possible bit values set:

    • If the bit field is set to DOT11_EXTSTA_ATTRIBUTES_SAFEMODE_OID_SUPPORTED with no other bits set, the miniport driver implements the 802.11 safe mode of operation.
    • If the bit field is set to DOT11_EXTSTA_ATTRIBUTES_SAFEMODE_CERTIFIED, the network adapter/miniport combination has received a validation certificate from the National Institute of Standards and Technology (NIST) under Federal Information Processing Standards (FIPS) Publication 140-2, Security Requirements for Cryptographic Modules.

    This member is used together with OID_DOT11_SAFE_MODE_ENABLED.

  • uNumSupportedCountryOrRegionStrings
    The number of country/region strings that are supported by the 802.11 station. If the 802.11 station supports multiple regulatory domains as specified by the IEEE 802.11d-2001 standard, each countr/region string identifies a regulatory domain supported by the 802.11 station.

    If the 802.11 station does not support the IEEE 802.11d-2001 standard, the miniport driver must set uNumSupportedCountryOrRegionStrings to zero.

  • pSupportedCountryOrRegionStrings
    A pointer to an array of 802.11d country/region strings that are supported by the 802.11 station. Each entry in the array is formatted as a DOT11_COUNTRY_OR_REGION_STRING structure.
  • uInfraNumSupportedUcastAlgoPairs
    The number of authentication and cipher algorithms that are supported by the 802.11 station for sending and receiving unicast packets when the station is configured for operation in an infrastructure basic service set (BSS) network.

Remarks

The NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure contains a member (pExtSTAAttributes) that specifies the address of a DOT11_EXTSTA_ATTRIBUTES structure. When the miniport driver calls NdisMSetMiniportAttributes, the driver sets the MiniportAttributes parameter to the address of a driver-allocated block of memory that contains an NDIS_MINIPORT_ADAPTER_NATIVE_802_11_ATTRIBUTES structure together with the DOT11_EXTSTA_ATTRIBUTES structure.
