Hi John and All,
 
I want to record the ts_longretry values for evey UDP DATA packet transmitted. I noticed that ts_longretry also records the management packet such as beacon, prob response.
 
How can I filter out this kind of ts_longretry values and only retain those values for DATA packets? Any hint will be greatly appreciated! 
 
Thanks!

If you enable rts/cts for a packet, the ts_shortretry field in ath_tx_status
should tell you the number of times an rts was sent but no cts was received.
