With this change, quiet period for QCA6174/QCA9377 can be also set/get via debugfs. Usage: To set quiet period: echo > /sys/kernel/debug/ieee80211/phyX/ath10k/quiet_period To get the current quiet period: cat /sys/kernel/debug/ieee80211/phyX/ath10k/quiet_period This change has been verified with QCA6174 hw3.2(fw: WLAN_RM.4.4.1-00102-QCARMSWP-1).
