我试图在版本2.5中使用hostapd与ACS。 为了做到这一点，我使用了以下configuration文件：
interface=wlp2s0 driver=nl80211 ssid=ap-example hw_mode=g channel=acs_survey macaddr_acl=0 ignore_broadcast_ssid=0 auth_algs=1 wpa=3 wpa_passphrase=ap-example wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP
我用CONFIG_ACS = y标志构build了hostapd，但是当我尝试启动服务时，出现以下错误：
$ ./hostapd /etc/hostapd/hostapd.conf Configuration file: /etc/hostapd/hostapd.conf ACS: Automatic channel selection started, this may take a bit wlp2s0: interface state UNINITIALIZED->ACS wlp2s0: ACS-STARTED ACS: Unable to collect survey data ACS: All study options have failed Interface initialization failed wlp2s0: interface state ACS->DISABLED wlp2s0: AP-DISABLED ACS: Possibly channel configuration is invalid, please report this along with your config file. ACS: Failed to start wlp2s0: AP-DISABLED hostapd_free_hapd_data: Interface wlp2s0 wasn't started nl80211: deinit ifname=wlp2s0 disabled_11b_rates=0 wlp2s0: interface state DISABLED->DISABLED wlp2s0: interface state DISABLED->DISABLED wlp2s0: AP-DISABLED hostapd_free_hapd_data: Interface wlp2s0 wasn't started
当然，我用root权限运行这个。 我在hostapd软件包的defconfig文件中看到，只有一些驱动程序支持自动频道订阅。
任何人都知道我的configuration发生了什么？ 在hostapd项目wiki中是否存在支持驱动程序的关系或类似的东西？
