Public bug reported:
I experience a very poor 802.11ac performance of a QCA6174 Wireless card
(Killer Wireless 1535).
This is a dev version of Zesty with a recently released 4.10 kernel:
uname -r
4.10.0-9-generic
dpkg -l linux-firmware | grep ii

Kernel modules: ath10k_pci
-----------------------------------------
Testing wireless speed with RT-87U 802.11ac router shows that the speed
is only 27.3 megabits per second which is very low for an 802.11ac card:
iperf -c rtr
------------------------------------------------------------

------------------------------------
For comparison, on the same network (from the same distance to the
router) I have the following result with an Intel's card (on a 4.8
kernel, different laptop):
UX32LN:~$ lspci | grep 7260

200 Mbps is much better.
