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