See: http://wireless.kernel.org/en/developers/Documentation/mac80211/RateControl/minstrel/

Analysis of information showed that the system was sampling too hard at some rates. For those rates that never work (54mb, 500m range) there is no point in retrying 10 sample packets (< 6 ms time). Consequently, for the very low probability rates, we try at most twice when fails and not sample more than 4 times.
