struct ieee80211_key(9)

NAME

struct_ieee80211_key_conf - key information

struct ieee80211_key_conf {
  enum ieee80211_key_alg alg;
  u8 hw_key_idx;
  u8 flags;
  s8 keyidx;
  u8 keylen;
  u8 key[0];
};

alg: The key algorithm.
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

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