[LEDE-DEV] [PATCH] Support Candela-Tech ath10k and ath9k out-of-tree driver.

[David Lang]

I'll point out that there is a lot of work being done on these drivers right now 
in terms of making significant changes to how they do buffering that in 
increasing network speed as well as reducing latency

search the follwoing lists for [make-wifi-fast] to see the details and 
benchmarks
make-wifi-fast at lists.bufferbloat.net, ath9k-devel at venema.h4ckr.net,linux-wireless at vger.kernel.org
