I forgot to mention that I'm using madwifi, and I'm familiar with the fact that the HAL is in binary form only.
I'd just like to know in which files/functions the RTS/CTS,DATA & ACK frames are constructed.
I believe this happens before the frames are delivered to the HAL, correct?
 
Thanks You,
Francisco Fernandes
