This patch restructures the rc_stats debugfs table of Minstrel in order to achieve better human readability. A new layout of the statistics and a new header is added. In addition to the old layout there are two new columns of information added: "idx" - representing the rate index of each rate in mac80211 which can be used to set specific rates as fixed rate via debugfs "airtime" - the tx-time in micro seconds that a 1200 Byte packet takes to be transmitted over the air at the given rate The old layout of rc_stats: rate tpt eprob *prob ret *ok(*cum) ok( cum) DP 1 0.9 93.5 100.0 1 0( 0) 2( 2) 2 0.4 40.0 100.0 0 0( 0) 4( 10) 5.5 0.0 0.0 0.0 0 0( 0) 0( 0) ... is chaged into this new layout: best _______rate_____ __statistics__ ________last_______ ______sum-of________ rate [name idx tx-time] [ ø(tp) ø(prob)] [prob.|retry|suc|att] [#success | #attempts] DP 1 0 9738 0.9 93.5 100.0 1 1 1 2 2 2 1 4922 0.4 40.0 100.0 1 0 0 4 10 5.5 2 1858 0.0 0.0 0.0 2 0 0 0 0 ...
