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



NAME
       struct_ieee80211_key_conf - key information

SYNOPSIS
       struct ieee80211_key_conf {
         atomic64_t tx_pn;
         u32 cipher;
         u8 icv_len;
         u8 iv_len;
         u8 hw_key_idx;
         u8 flags;
         s8 keyidx;
         u8 keylen;
         u8 key[0];
       };

MEMBERS
       tx_pn
           PN used for TX keys, may be used by the driver as well if it needs to do software PN
           assignment by itself (e.g. due to TSO)

       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) data block: -
           Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC Key (64 bits) -
           Temporal Authenticator Rx MIC Key (64 bits)

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