Just a quick note: a while ago, somebody proposed
(http://lkml.iu.edu/hypermail/linux/kernel/1202.3/02307.html) a
enhanced version of this algorithm that would, according to the related
research and paper [1], outperform Minstrel in most cases. The patch
was not accepted as comments (mostly related to coding style, but not
only that) weren't addressed by the sender. I then never had the time
to seriously look into it. My understanding is that the amended
algorithm would spare some air time compared to Minstrel, and thus it
could provide marginally better performance.

So, maybe somebody is interested in looking into that. Otherwise, yes,
let's drop it.

Performance of mac80211 rate control mechanisms. In Proceedings of MSWiM
2011, October 31-November 4, 2011 Miami Beach, FL, USA. Which used to be
available at http://www.itee.uq.edu.au/∼uqwyin/publications/MSWiM2011,
but was then removed. I can send the PDF if anybody wants it, it carries
no copyright or distribution terms whatsoever.
