Are you sure it was minstrel_ht, or could it also have been minstrel
(the legacy version)? I don't have any recent RvR test results, however
on every single link that I tested both rate control modules on (leaving
everything else unchanged), minstrel_ht got slightly better results.
Additionally, I occasionally get asked for help on debugging low
throughput issues, and many of the people asking me have reported that
simply switching to minstrel_ht fixed these issues in their tests.

I would also like to see some real RvR tests comparing both, preferably
before this gets merged, which is why I sent it as RFC.
