FAQ1: Can the driver connect to STA/SofAP during the ATE process?
No, it can't do that.
During the ATE process, the driver will be switched into test mode. At mean time, the driver can't work
as normal mode. It only processes specific ATE commands for testing WiFi RF purpose. 

FAQ2: In the ATE mode, can the driver perform WiFi throughput test?
No, ATE is only for testing purpose.

FAQ3: How to turn on debug message in the driver?
To enable debug message, # iwpriv ra0 set Debug=3

FAQ4: How can I verify TX power delta?
Please check the ATE command sequence as below!
iwpriv ra0 set ATE=ATESTART
iwpriv ra0 set ATETXMODE=2
