The max retry rates number for iwl4965 is 16. See iwl-commands.h for
more details:
a) Use the initial rate for only one entry.
b) For each following entry, reduce the rate to next lower available
rate, until reaching the lowest available rate.
c) When reducing rate, also switch antenna selection.
d) Once lowest available rate is reached, repeat this rate until
rate table is filled (16 entries), switching antenna each entry.
Thanks,
