How
 old is your hostapd build? Do you have country code, ieee80211d, and 
ieee80211hset in hostapd.conf? I've been running ath10k in AP mode on 
DFS-channels since february (10.1-branch firmware, VHT80).

>> Does it mean that ath10k does not support configured channel ???? The reason I want to do it by command "iw" because it has more options than hostapd (iw wlan0 set freq <control freq> [20|40|80|80+80|160] [<center freq 1>] [<center freq 2>] )
