From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx> [ Upstream commit 8d350c14ee5eb62ecd40b0991248bfbce511954d ] As expected, when the device detect a MMIC error, it returns a specific status. However, it also strip IV from the frame (don't ask me why). So, with the current code, mac80211 detects a corrupted frame and it drops it before it handle the MMIC error. The expected behavior would be to detect MMIC error then to renegotiate the EAP session. So, this patch correctly informs mac80211 that IV is not available. So, mac80211 correctly takes into account the MMIC error.
