Hello! Are you working on 802.11 MAC? If yes I need some help regarding the interface queues. I want to differentiate the authentication packets from others and give priority to them. But in the case statement of priqueue.cc, I am not able to identify the MAC AUTH packet. I got the MAC header only from the function hdr_cmn802_11 only. But still I'm facing the problem. Please let me know anything about this so that I can proceed with my project work. It is very urgent, please do take some time if you happen to know anything about it.
