cfg80211_michael_mic_failure - notification of Michael MIC failure (TKIP)

void cfg80211_michael_mic_failure(struct net_device *  dev , const u8 *  addr , enum nl80211_key_type  key_type , int  key_id , const u8 *  tsc , gfp_t  gfp );

dev
    network device

addr
    The source MAC address of the frame

key_type
    The key type that the received frame used

key_id
    Key identifier (0..3). Can be -1 if missing.

tsc
    The TSC value of the frame that generated the MIC failure (6 octets)

gfp
    allocation flags

This function is called whenever the local MAC detects a MIC failure in a received frame. This matches with MLME-MICHAELMICFAILURE.indication primitive.
