STRUCT IEEE80211_KEY(9)	   Advanced driver interface   STRUCT IEEE80211_KEY(9)

NAME
       struct_ieee80211_key_conf - key information

SYNOPSIS
       struct ieee80211_key_conf {
	 u32 cipher;
	 u8 icv_len;
	 u8 iv_len;
	 u8 hw_key_idx;
	 u8 flags;
	 s8 keyidx;
	 u8 keylen;
	 u8 key[0];
       };

MEMBERS
       cipher
	   The key´s cipher suite selector.

       icv_len
	   The ICV length for this key type

       iv_len
	   The IV length for this key type

       hw_key_idx
	   To be set by the driver, this is the key index the driver wants to
	   be given when a frame is transmitted and needs to be encrypted in
	   hardware.

       flags
	   key flags, see enum ieee80211_key_flags.

       keyidx
	   the key index (0-3)

       keylen
	   key material length

       key[0]
	   key material. For ALG_TKIP the key is encoded as a 256-bit (32
	   byte)

DESCRIPTION
       This key information is given by mac80211 to the driver by the set_key
       callback in struct ieee80211_ops.

DATA BLOCK
       - Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC
       Key (64 bits) - Temporal Authenticator Rx MIC Key (64 bits)
