3/12/2014

This 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 it is 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.
