This patch moves Minstrels and Minstrel-HTs per-rate throughput
calculation (EWMA(thr)) into a dedicated function to be called.
Therefore the variable "unsigned int cur_tp" within struct

This patch adds the statistical descriptor "standard deviation"

deviation (SD) is calculated as exponential weighted moving
standard deviation (EWMSD) and its current value is added
This patch series adds several improvements to the readability, the
output format of rc_stats and the calculated statistics of Minstrel

I do not see how a TSO patch could hurt a flow not using TSO/GSO.

Hi Johannes,
Just a quick question about the bitrate info shown with 'iw link'. I
assume the MCS info reported is the MCS related to the bitrate number so
the current/last MCS used and not some maximum MCS.
