mac80211: enhance readability of Minstrel-HTs rc_stats output
This patch restructures the rc_stats debugfs table of Minstrel-HT 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:
type rate tpt eprob *prob ret *ok(*cum) ok( cum)
HT20/LGI MCS0 5.6 100.0 100.0 1 0( 0) 1( 1)
HT20/LGI B MCS1 10.5 100.0 100.0 0 0( 0) 1( 1)
HT20/LGI A MCS2 14.8 100.0 100.0 0 0( 0) 1( 1)
...
is changed into this new layout:
best ________rate______ __statistics__ ________last_______ ______sum-of________
mode guard # rate [name idx airtime] [ ø(tp) ø(prob)] [prob.|retry|suc|att] [#success | #attempts]
HT20 LGI 1 MCS0 0 1480 0.0 0.0 0.0 1 0 0 0 0
HT20 LGI 1 B MCS1 1 740 10.5 100.0 100.0 0 0 0 1 1
