Johannes,
Thank you for that. I need to make a quick hack to send an invalid
MIC packet from another device to test the countermeasures. Should I
submit a new patch with this change when I've completed testing or are
you already prepared to do so?

I am using an rt5350 SoC using the rt2x00 driver. We were doing
WiFi-alliance certification testing on our device and the it wasn't
issuing countermeasures appropriately.
Your assumption is correct. I had overlooked that devices using this
driver have hardware decoding and the driver sets

In order to allow wpa_supplicant to correctly identify a perceived WPA TKIP key
recovery attack the michael MIC must be checked before the packet decode is
attempted. A packet with an invalid MIC will always fail a decrypt check which
previously was being checked first. Therefore the MIC failure
