Key information
Usage
struct ieee80211_key_conf {

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