OID_DOT11_CURRENT_OPTIONAL_CAPABILITY

When queried, the OID_DOT11_CURRENT_OPTIONAL_CAPABILITY object identifier (OID) requests that the miniport driver return the state of the optional wireless LAN (WLAN) capabilities supported by the 802.11 station.

Optional WLAN capabilities are not required for the 802.11 station to operate within a basic service set (BSS) network. However, once enabled, these capabilities could provide better performance within the BSS network. When OID_DOT11_OPTIONAL_CAPABILITY is queried, the miniport driver specifies the types of optional WLAN capabilities supported by the 802.11 station.

The data type for OID_DOT11_CURRENT_OPTIONAL_CAPABILITY is the DOT11_CURRENT_OPTIONAL_CAPABILITY structure.



    typedef struct _DOT11_CURRENT_OPTIONAL_CAPABILITY {
         ULONG uReserved;
         BOOLEAN bDot11CFPollable;
         BOOLEAN bDot11PCF;
         BOOLEAN bDot11PCFMPDUTransferToPC;
         BOOLEAN bStrictlyOrderedServiceClass;
    } DOT11_CURRENT_OPTIONAL_CAPABILITY,   *PDOT11_CURRENT_OPTIONAL_CAPABILITY;
  

This structure includes the following members:

uReserved

This member is reserved. The miniport driver must not modify the value of this member.

bDot11CFPollable

Specifies whether the 802.11 station can respond to an 802.11 CF-Poll frame. The miniport driver should return the value of the IEEE 802.11 dot11CFPollable management information base (MIB) object. For more information about this MIB object, see OID_DOT11_CF_POLLABLE.

bDot11PCF

Specifies whether the 802.11 station has enabled the Point Coordination Function (PCF). For more information about PCF, refer to clauses 9.2.3 and 9.4 of the IEEE 802.11-2012 standard.

bDot11PCFMPDUTransferToPC

Specifies whether the 802.11 station has enabled delivery of received PCF MAC protocol data unit (MPDU) frames to the operating system.

Note  

If the miniport driver sets this member to TRUE, the miniport driver must also set the bDot11PCF member to TRUE.

bStrictlyOrderedServiceClass

Specifies whether the 802.11 station has enabled the StrictlyOrdered service class for MSDU packet ordering. For more information about the StrictlyOrdered service class, refer to clause 5.1.3 of the IEEE 802.11-2012 standard.

If the miniport driver is operating in Extensible Station (ExtSTA) mode, OID_DOT11_CURRENT_OPTIONAL_CAPABILITY is a query-only OID and cannot be used to enable or disable the optional WLAN capabilities supported by the 802.11 station. However, the independent hardware vendor (IHV) can define a proprietary NIC-specific extension to change the optional WLAN capabilities. After its been defined, a service supplied by the IHV can issue the NIC-specific extension to the miniport driver. For more information about NIC-specific extensions, see OID_DOT11_NIC_SPECIFIC_EXTENSION.
