  USHORT  usEtherType;
  USHORT  usExemptionActionType;
  USHORT  usExemptionPacketType;
} DOT11_PRIVACY_EXEMPTION, *PDOT11_PRIVACY_EXEMPTION;

Members

  • usEtherType

  • usExemptionActionType

    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.
