Collecting CSI information

[Okhwan Lee]

 Hi all, 

I have one question about firmware update.  
As far as I know, the firmware is basically distributed from the Qualcom-Atheros.  
Some modified version of the official firmware is distributed from open source community.  

Is there any QCA9880 firmware which supports to collect and report CSI information (measured at VHT-LTF),  
like IWL5300 does (http://dhalperi.github.io/linux-80211n-csitool/)?
