## NAME

cfg80211\_michael\_mic\_failure - notification of Michael MIC failure (TKIP)

## SYNOPSIS

**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***);**

## ARGUMENTS

*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*
