pounding the ath10k flat now

top screenshot, and some quick measurements will return to the ath9k later...

one of the reasons why I was interested in the softirq patch of
felix's was watching softirq eat so much cpu here... which sqm-scripts
also exercises....

from what I can tell, the fq_codel and intermediate queues for ath10k
is not in this stuff (yet).

(I don't care(yet)! Establishing a baseline with newer hardware here I am!)
