The TX throughput on QCA6174 Wireless card (Killer Wireless 1535)
under 5Ghz network is poor, the test result is around 10 ~ 20 Mbits/sec.
The fix is suggested by Qualcomm, and it works.
Without the patch, the 5GHz network speed is pretty low
0.0-120.1 sec 271 MBytes 18.9 Mbits/sec
0.0-120.2 sec 141 MBytes 9.86 Mbits/sec
After applied the patch
0.0-120.0 sec 2.04 GBytes 146 Mbits/sec
0.0-120.0 sec 1.17 GBytes 83.6 Mbits/sec
Qualcomm doesn't want to upstream this fix, and the ath10k driver architecture
changes a lot after kernel 4.4 and can't apply this fix. So, I would suggest
to have this fix as SAUCE patch only included in Ubuntu kernel.
