};
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)
