Two autotests: 1. Tests SA Query procedure when the AP goes down. In this case the AP goes down ungracefully, now allowing it to send out any deauth frames. When the AP comes back up, IWD still thinks its connected. The AP will then send unprotected disassociate frames so the client can re-connect. This kicks off the SA Query procedure, which the AP will not respond to. At this point we can deauth and reconnect to the AP. 2. Test SA Query procedure when a disassociate frame has been spoofed. In this case we receive an unprotected disassociate frame and start SA Query. The AP should then respond to the SA query within the timeout. We then know the frame was spoofed and can remain connected.
