		const u8 *	kck,
		int	ver,
		const u8 *	dest,
		u16	proto,
		u8 *	msg,
		size_t	msg_len,
		u8 *	key_mic
	)

Send WPA/RSN EAPOL-Key message.

Parameters:

	sm	Pointer to WPA state machine data from wpa_sm_init()
	kck	Key Confirmation Key (KCK, part of PTK)
	ver	Version field from Key Info
	dest	Destination address for the frame
	proto	Ethertype (usually ETH_P_EAPOL)
	msg	EAPOL-Key message
	msg_len	Length of message
	key_mic	Pointer to the buffer to which the EAPOL-Key MIC is written
