SYNOPSIS

9       struct ieee80211_key_conf {
10         enum ieee80211_key_alg alg;
11         u8 icv_len;
12         u8 iv_len;
13         u8 hw_key_idx;
14         u8 flags;
15         s8 keyidx;
16         u8 keylen;

MEMBERS

21       alg
22           The key algorithm.
23
24       icv_len
25           The ICV length for this key type
26
27       iv_len
28           The IV length for this key type
29
30       hw_key_idx
31           To be set by the driver, this is the key index the driver wants to
32           be given when a frame is transmitted and needs to be encrypted in
33           hardware.
34
35       flags
36           key flags, see enum ieee80211_key_flags.
37
38       keyidx
39           the key index (0-3)
40
41       keylen
42           key material length
43
44       key[0]
45           key material. For ALG_TKIP the key is encoded as a 256-bit (32
46           byte)
47

DESCRIPTION

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

DATA BLOCK

53       - Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC
54       Key (64 bits) - Temporal Authenticator Rx MIC Key (64 bits)
