Hi Lin,

I dont think ts_longretry keeps a count for management packets as they are broadcast packets.Its a count for data packets only.From my experiments i noted each data packet is retransmitted 10 times before finally been dropped.802.11 suggest's a separate retry counter for short and long MSDU and MMPDU.

By 802.11:

1. SSRC increases by one for each failed MPDU whose length is <= dot11RTSThreshold ( or RTS in RTS/CTS scheme)
2. SLRC increases by one for each failed MPDU whose length is > dot11RTSThreshold
3.Both counters are reset upon a successful MPDU
4.Retry is aborted when SSRC>=dot11ShortRetryLimt =7 or
SLRC>=aLongRetryLimit=4


Its is interesting to note John Bicket say that the ts_shortretry field in ath_tx_status tell's you the number of times an rts was sent but no cts was received.

Thanks,
Sritej
