Thanks much for your help.
However, I have looked at my driver code and
did not find any implementations such as wiphy_ext_feature_set()
It seems not simple to apply your patch into my version of ath10k device 
I am currently using backports-3.16-rc1-1 for ath10k device driver code
in order to match the kernel version v3.16 for Ubuntu 14.04.02.

Could you tell me the version of kernel and ath10k device driver of your
test configuration?
Or is there any way to apply your version of patch code into linux 
kernel v3.16?
(I expect the version will be much more recent one than mine)
