/**
 * set_key - Configure encryption key
 * @ifname: Interface name (for multi-SSID/VLAN support)
 * @priv: private driver interface data
 * @alg: encryption algorithm (%WPA_ALG_NONE, %WPA_ALG_WEP,
 *	%WPA_ALG_TKIP, %WPA_ALG_CCMP, %WPA_ALG_IGTK, %WPA_ALG_PMK);
 *	%WPA_ALG_NONE clears the key.
 * @addr: address of the peer STA or ff:ff:ff:ff:ff:ff for
 *	broadcast/default keys
 * @key_idx: key index (0..3), usually 0 for unicast keys; 0..4095 for
 *	IGTK
 * @set_tx: configure this key as the default Tx key (only used when
 *	driver does not support separate unicast/individual key
 * @seq: sequence number/packet number, seq_len octets, the next
 *	packet number to be used for in replay protection; configured
 *	for Rx keys (in most cases, this is only used with broadcast
 *	keys and set to zero for unicast keys)
 * @seq_len: length of the seq, depends on the algorithm:
 *	TKIP: 6 octets, CCMP: 6 octets, IGTK: 6 octets
 * @key: key buffer; TKIP: 16-byte temporal key, 8-byte Tx Mic key,
 *	8-byte Rx Mic Key
 * @key_len: length of the key buffer in octets (WEP: 5 or 13,
 *	TKIP: 32, CCMP: 16, IGTK: 16)
 *
 * Returns: 0 on success, -1 on failure
 *
 * Configure the given key for the kernel driver. If the driver
 * supports separate individual keys (4 default keys + 1 individual),
 * addr can be used to determine whether the key is default or
 * individual. If only 4 keys are supported, the default key with key
 * index 0 is used as the individual key. STA must be configured to use
 * it as the default Tx key (set_tx is set) and accept Rx for all the
 * key indexes. In most cases, WPA uses only key indexes 1 and 2 for
 * broadcast keys, so key index 0 is available for this kind of
 * configuration.
 *
 * Please note that TKIP keys include separate TX and RX MIC keys and
 * some drivers may expect them in different order than wpa_supplicant
 * is using. If the TX/RX keys are swapped, all TKIP encrypted packets
 * will tricker Michael MIC errors. This can be fixed by changing the
 * order of MIC keys by swapping te bytes 16..23 and 24..31 of the key
 * in driver_*.c set_key() implementation, see driver_ndis.c for an
 * example on how this can be done.
