This patch seems to fix the issue on Ubuntu 4.4 kernel.
The ath10k driver structure has been changed after 4.4, so this fix can't apply
to 4.8+ kernel,
and it looks like should stay in 4.4 kernel only.

Status in linux package in Ubuntu:
In Progress
Bug description:
TX throughput is not good in Ubuntu in IEEE 802.11ac mode.
Measured Rx 60Mbit/s and Tx 12Mbit/s with Ubuntu
Windows 10 (1607) performs much better with on transmit side Rx 73MBit/s and
Tx 62MBit/s using the same hardware setup.
Same result with WPA2 disabled in unencrypted mode.
