QCA6174 hw2.1 firmware, take two?

[Gregor Plata]

Hi all,

the solution described in the bug report 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184 (comment #150) 
works perfectly for me. Wi-fi is stable without any drops and the 4.1.0-rc6-
wl-ath kernel doesn't cause any  issues but the wi-fi performance comes only 
to about 35%-40% of the performance on windows on the same machine downloading 
the same file from the same server .

best regards
Gregor
