Comment 350 for bug 1383184

Still unsupported as of 16.04 and yakkety for my hardware (Dell Latitude E7270).

The workaround involves replacing "/lib/firmware/ath10k/QCA6174/hw3.0/board.bin" with a version from Killer Networking's website, as per:

http://www.killernetworking.com/product-support/knowledge-base/17-linux

The required file is directly available at:

http://www.killernetworking.com/support/K1535_Debian/board.bin

The machine is a Dell Latitude E7270. Here's the lspci output:
