Very low throughput with QCA9880

Thanks again for your help Sebastian.
You were correct. My Ubuntu 14.04 LTS install was using wireless-regdb
version 2013.02.13. After switching to 16.04 LTS which uses version is
2015.07.20, I am now able to associate to my AP at vht80. Upstream UDP
throughput is now 450 Mbps and TCP (with reno congestion control) is
around 260 Mbps.
With that problem solved, I'd like to see if it is possible to
optimize further to achieve better TCP performance. Any suggestions
you might have would be appreciated.
Regards,
Martin
