[ath9k-devel] decrease speed ath9k last kernel updates

Hi, i've been using archlinux x86_64 for years and ath9k always worked fine,
but with the lasts kernel updates speciallly 4.4.5-1, perhaps before.

Well, my Wireless speed with my NIC Qualcomm Atheros AR928X that uses ath9k,
dropped dramatically to a bitrate 5,5Mb/s, and  download speed less than
100Kb/s, before last kernel updates i had near 1024Kb/s. No possible to work
on network with enough speed.

I made some tests with the same machine and same network and same conditions
but different distro (slitaz) and ath9k worked fine. So i suspected about
the last kernel updates on archlinux.

So i install other old kernel, lts (linux-lts) 4.1.20-1-lts, and ath9k came
back to the life and speed. So....

I like to report a bug at least on 4.4.5-1 archlinux kernel about ath9k, but
is here the right place?

If any dev want more info I had screenshots with info about ath9k module,
with archlinux 4.4.5-1, slitaz (kernel 2.6xx), and now with lts kernel
archlinux 4.1.20-1-lts.

thanks in advance
