The main file I focused on was net/mac80211/rc80211minstrel.c, but I have tried forcing retry values through the other portions of the code. I have tried setting the counts in the MRR array (ar[i].count) in the minstrel_get_rate function, but that hasn't appeared to work, additionally I tried limiting the max retry count. I have had luck in altering the rate used by changing the index value fed into ar[i].idx. Maybe my issue is with the MRR array. If I want the driver to try the packet once and only once , if it fails (no ack) then give up, what would be the changes to make to the MRR array. My understanding is I would set the ar[0].idx value the index for the rate I want (this is not an issue), but then setting the ar[0].count, do I set it to 1 to try and send it once, or is count simply the number of retries to do after the initial send. Also, if I set the next entry in the MRR array ar[1].idx=-1 so as to not try any rate, and then the count to 0 does this disable the rest of the MRR array, or is it possible the hardware is populating the array with other values? -Andrew On Thu, Feb 25, 2010 at 12:51 PM, Bob Copeland <me@xxxxxxxxxxxxxxx> wrote: > On Thu, Feb 25, 2010 at 9:40 AM, Andrew Blaich <ablaich@xxxxxxxxx> wrote: >> Hi everyone, >> >> I have been attempting, unsuccessfully, to alter the number >> retransmissions any particular transmission rate uses.
