2013-04-22mac80211/minstrel_ht: use the new rate control APIFelix Fietkau
Pass the rate selection table to mac80211 from minstrel_ht_update_stats. Only rates for sample attempts are set in info->control.rates. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-03-06mac80211: merge value scaling macros of minstrel_ht and minstrelThomas Huehn
Both minstrel versions use individual ways to scale up integer values to perform calculations. Merge minstrel_ht's scaling macros into minstrels header file and use them in both minstrel versions.

2013-03-06mac80211/minstrel_ht: increase sampling frequency of some slower ratesFelix Fietkau
If a rate is below the max_tp_rate, sample it frequently if: - it is above max_tp_rate2, or - it is above max_prob_rate and is a candidate for max_prob_rate (has fewer streams than max_tp_rate). This helps the retry chain recover more quickly from bad statistics caused by collisions or interference, and slightly reduces throughput fluctuations with higher rates.

2013-02-13mac80211/minstrel_ht: add support for using CCK ratesFelix Fietkau
When MCS rates start to get bad in 2.4 GHz because of long range or strong interference, CCK rates can be a lot more robust. This patch adds a pseudo MCS group containing CCK rates (long preamble in the lower 4 slots, short preamble in the upper slots).
