OID_DOT11_SHORT_SLOT_TIME_OPTION_ENABLED

When queried, the OID_DOT11_SHORT_SLOT_TIME_OPTION_ENABLED object identifier (OID) requests that the miniport driver return the value of the IEEE 802.11g dot11ShortSlotTimeOptionEnabled management information base (MIB) object for the current PHY type on the 802.11 station.

This MIB object specifies whether the current PHY type has enabled the 802.11g short slot time option. For more information about short slot time option, refer to Clause 7.3.1.4 of the IEEE 802.11g-2003 standard.

Note  Support for this OID is mandatory if the NIC supports the dot11_phy_type_erp PHY type. For more information about how the miniport driver specifies its list of supported PHY types, see OID_DOT11_SUPPORTED_PHY_TYPES.

The data type for this OID is a BOOLEAN value. A value of TRUE indicates that the current PHY type has the 802.11g short slot time option enabled.

The dot11ShortSlotTimeOptionEnabled MIB object is only valid for the Extended-rate PHY (ERP) type. If the current PHY type is not set to dot11_phy_type_erp, the miniport driver must fail the query request by returning NDIS_STATUS_INVALID_DATA from its MiniportOidRequest function.

If the miniport driver is operating in Extensible Station (ExtSTA) mode, the current PHY type is determined through the ExtSTA msDot11CurrentPhyID MIB object. This MIB object specifies the index of the current PHY type within the 802.11 station's list of supported PHY types. For more information about this MIB object, see OID_DOT11_CURRENT_PHY_ID.

Note  A Native 802.11 miniport driver that is designed to run on the Windows Vista or Windows Server 2008 operating systems must always reset this 802.11 MIB OID to its default value. This is the case regardless of the value of the bSetDefaultMIB member of the DOT11_RESET_REQUEST structure. This requirement applies to a miniport driver that, in a call to the NdisMSetMiniportAttributes function, sets MiniportAttributes -> Native_802_11_Attributes -> Header -> Revision to NDIS_MINIPORT_ADAPTER_802_11_ATTRIBUTES_REVISION_1.
