These frames are used for verifying that a specific SA and protected link is in functional state between two devices. The IEEE 802.11 standard defines only a case that uses individual MAC address as the destination. While there is no explicit rule on the receiver to ignore other cases, it seems safer to make sure group-addressed frames do not end up resulting in undesired behavior. As such, drop such frames instead of interpreting them as valid SA Query Request/Response. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
