pic at mcs4 attached. Note the labling is wrong, the "HT20" stuff was against
the privious lede-mainline firmware, against the 2.4ghz stuff, so this
data is directly comparable.
Note, we are testing 3 changed variables here - the reduced codel
target, the much saner quantum, and the airtime fairness code... and I
think but am not sure, I was using felix's new softirq patch in the
previous testing
and I still need to get around to airtime fairness... but need more
stuff bolted down first.

I'm not crazy, I run the rrul test at the conclusion of the run. Which this was.
I'll go run it on a fresh boot but...

Seems to come back after a while.

It appears that attempts to exercise CS5 and CS1 fail entirely judging
from the statio aqm file and the ath9k xmit (or the driver is
reloading and wiping out these stats). I'll poke at it harder.
