  NDIS_OBJECT_HEADER  Header;
  ULONG  uScanSSIDListSize;

} DOT11_EXTSTA_CAPABILITY, *PDOT11_EXTSTA_CAPABILITY;

Members

  • Header
    The type, revision, and size of the DOT11_EXTSTA_CAPABILITY_PARAMETERS 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_DEFAULT

    Revision

    This member must be set to DOT11_EXTSTA_CAPABILITY_REVISION_1

    Size

    This member must be set to sizeof(DOT11_EXTSTA_CAPABILITY)

  • uScanSSIDListSize
    The maximum number of service set identifiers (SSIDs) that are supported by the 802.11 station for scan operations. The 802.11 station must support an SSID list of at least four entries.

    The SSID list that the 802.11 station uses for scanning is specified when OID_DOT11_SCAN_REQUEST is set.

  • uDesiredBSSIDListSize
    The maximum number of entries in the desired list of basic service set identifiers (BSSIDs) that is supported by the 802.11 station. The 802.11 station must support a BSSID list that has at least one entry.

    For more information about the desired BSSID list, see OID_DOT11_DESIRED_BSSID_LIST.

  • uDesiredSSIDListSize
    The maximum number of entries in the desired SSID list that is supported by the 802.11 station. The 802.11 station must support a desired SSID list that has at least one entry.

    For more information about the desired SSID list, see OID_DOT11_DESIRED_SSID_LIST.

  • uExcludedMacAddressListSize
    The maximum number of entries in the excluded MAC address list that is supported by the 802.11 station. The 802.11 station must support an excluded MAC address list that has at least four entries.

    For more information about the desired excluded MAC address list, see OID_DOT11_EXCLUDED_MAC_ADDRESS_LIST.

  • uPrivacyExemptionListSize
    The maximum number of entries in the privacy exemption list supported by the 802.11 station. The 802.11 station must support a privacy exemption list that has at least one entry.

    For more information about the privacy exemption list, see OID_DOT11_PRIVACY_EXEMPTION_LIST.

  • uKeyMappingTableSize
    The maximum number of cipher key-mapping keys supported by the 802.11 station. It is recommended that the 802.11 station support at least 32 key-mapping keys.

    For more information about key mapping keys, see OID_DOT11_CIPHER_KEY_MAPPING_KEY.

  • uDefaultKeyTableSize
    The maximum number of cipher keys the 802.11 station supports for the default key and per-station default key tables.

    For standard 802.11 cipher algorithms, the 802.11 station must support a table size of at least four cipher keys. For cipher algorithms developed by the independent hardware vendor (IHV), the table size can be four or greater.

  • uWEPKeyValueMaxLength
    The maximum length, in bytes, of a WEP cipher key supported by the 802.11 station.

    The following table lists the minimum and maximum key lengths, in bytes, for the various WEP cipher enumerator values that are defined through DOT11_CIPHER_ALGORITHM:

    WEP Cipher

    Minimum Key Length

    Maximum Key Length

    DOT11_CIPHER_ALGO_WEP40

    5

    5

    DOT11_CIPHER_ALGO_WEP104

    13

    13

    DOT11_CIPHER_ALGO_WEP

    13

    Any length supported by the 802.11 station

  • 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.
