The IHV Extensions DLL calls the Dot11ExtSetExcludeUnencrypted function to enable or disable the wireless LAN (WLAN) adapter from excluding unencrypted packets it receives while enabled for cipher operations.
DWORD APIENTRY Dot11ExtSetExcludeUnencrypted( _In_opt_ HANDLE hDot11SvcHandle, _In_ BOOL bExcludeUnencrypted );
- hDot11SvcHandle [in, optional]
The handle used by the operating system to reference the WLAN adapter. This handle value was specified through a previous call to the Dot11ExtIhvInitAdapter IHV Handler function.
- bExcludeUnencrypted [in]
A Boolean value that, if set to TRUE, configures the WLAN adapter to exclude unencrypted packets.
If the call succeeds, the function returns ERROR_SUCCESS. Otherwise, it returns an error code defined in Winerror.h.
If the WLAN adapter is enabled to exclude unencrypted packets, the station must exempt received packets that match an entry in the station's current EtherType exemption list. The IHV Extensions DLL specifies the EtherType exemption list through calls to the Dot11ExtSetEtherTypeHandling function.
A call to the Dot11ExtSetExcludeUnencrypted function results in a set request of the OID_DOT11_EXCLUDE_UNENCRYPTED object identifier (OID) to the Native 802.11 miniport driver that manages the WLAN adapter.
