Important
WiFiCx is the new Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features. The WDI driver model is now in maintenance mode and will only receive high priority fixes.
The DOT11_PRIVACY_EXEMPTION structure defines a decryption exemption for a specified network EtherType.
Syntax
typedef struct DOT11_PRIVACY_EXEMPTION {
USHORT usEtherType;
USHORT usExemptionActionType;
USHORT usExemptionPacketType;
} DOT11_PRIVACY_EXEMPTION, *PDOT11_PRIVACY_EXEMPTION;
Members
usEtherType
The value of the IEEE EtherType in big-endian byte order.
usExemptionActionType
The type of exemption for the specified EtherType. The following exemption types are defined:
DOT11_EXEMPT_ALWAYS
The 802.11 station must discard the received packet if the Protected Frame subfield of the Frame Control field in the 802.11 MAC header is set to one.
DOT11_EXEMPT_ON_KEY_MAPPING_KEY_UNAVAILABLE
The 802.11 station must discard the received packet if a key-mapping key for the source MAC address is available and the Protected Frame subfield of the Frame Control field in the 802.11 MAC header is set to zero.
usExemptionPacketType
The type of packet that the exemption for the specified EtherType applies to. The following packet types are defined:
DOT11_EXEMPT_UNICAST
Exempt only unicast packets.
DOT11_EXEMPT_MULTICAST
Exempt only multicast or broadcast packets.
DOT11_EXEMPT_BOTH
Exempt all packet types.
Remarks
The 802.11 station's packet exemption list if configured through a set request of OID_DOT11_PRIVACY_EXEMPTION_LIST. For each packet the 802.11 station receives, it will apply the decryption exemption specified by the list entry with a usEtherType value that matches the EtherType of the packet.
