- * Function:	cmpk_message_handle_tx()

- * Overview:	Driver internal module can call the API to send message to
- *		firmware side. For example, you can send a debug command packet.
- *		Or you can send a request for FW to modify RLX4181 LBUS HW bank.
- *		Otherwise, you can change MAC/PHT/RF register by firmware at
- *		run time. We do not support message more than one segment now.
