Re: Frame Identification

In normal operation, the low level RTS/CTS/ACK frames are handled
directly in firmware/uCode, and are not passed up to the driver.
 
You could experiment to see if promiscuous mode passes them up.
 
To parse the type of frame, take a look in the frame control bytes in
the MAC header.  You might find some ideas in the ipw_report_frame()
function found in 3945 driver (never got ported to 2200).

	Hello there,
	 
	As part of my experiment with IPW2200BG WiFi card, I need to
monitor the type of frame received. For example, as you know, every DATA
transmission in IEEE 802.11 often involves RTS-CTS-DATA-ACK handshake
mechanism. Hence, whenever a node receives a frame, is there any for it
to determine whether it is an RTS, CTS, DATA or ACK frame. 
	 
	Thanks in advance for taking your invaluable time to answer my
question.
	 
	Best Regards,
	 
	Siva
