Description of problem: hostapd in Fedora 24 is built w/o ACS support, unlike hostapd in Fedora 25. From the F25 changelog : * Tue Apr 19 2016 Sascha Spreitzer <sspreitz> - 2.5-3 - Enable ACS feature (automatic channel switching) Could the f25 branch be merged into f24 and hostapd rebuilt please ? I verified it builds and run as expected with ACS support (using "fedpkg --release f24 mockbuild" from the f25 branch) Version-Release number of selected component (if applicable): hostapd-2.5-2.fc24 How reproducible: Always Steps to Reproduce: 1. install hostapd 2. configure it to use ACS 3. start hostapd Actual results: Log extract with F24 build : systemd[1]: Starting Hostapd IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator... hostapd[1502]: Configuration file: /etc/hostapd/hostapd.conf hostapd[1502]: ACS was disabled on your build, rebuild hostapd with CONFIG_ACS=y or set channel hostapd[1502]: wlan0: IEEE 802.11 Configured channel (0) not found from the channel list of current mode (1) IEEE 802.11g hostapd[1502]: wlan0: IEEE 802.11 Configured channel (0) not found from the channel list of current mode (1) IEEE 802.11g hostapd[1502]: wlan0: IEEE 802.11 Hardware does not support configured channel hostapd[1502]: wlan0: IEEE 802.11 Hardware does not support configured channel hostapd[1502]: Could not select hw_mode and channel.

Additional info: I am confident everything is there, but I guess a "thank you in advance" won't hurt :-)
