102 * bridge_ifname - Optional bridge interface name
104 * If the driver interface (ifname) is included in a Linux bridge
105 * device, the bridge interface may need to be used for receiving EAPOL
106 * frames. This can be enabled by setting this variable to enable
107 * receiving of EAPOL frames from an additional interface.

115 * This is used only when the driver supports a dedicated P2P Device
116 * interface that is not a network interface.

126 * daemonize - Run %wpa_supplicant in the background
131 * wait_for_monitor - Wait for a monitor program before starting

138 * If this and daemonize are set, process ID of the background process
139 * will be written to the specified file.
144 * wpa_debug_level - Debugging verbosity level (e.g., MSG_INFO)
149 * wpa_debug_show_keys - Whether keying material is included in debug
151 * This parameter can be used to allow keying material to be included
152 * in debug messages. This is a security risk and this option should
153 * not be enabled in normal configuration. If needed during

187 int wpa_debug_syslog;
190 * wpa_debug_tracing - Enable log output through Linux tracing

198 * dynamic interface addition to force a specific driver wrapper to be
201 char *override_driver;
204 * override_ctrl_interface - Optional ctrl_interface override
206 * This parameter can be used to override the ctrl_interface parameter
207 * in dynamic interface addition to force a control interface to be

216 * its internal entropy store over restarts.
222 * conf_p2p_dev - Configuration file used to hold the
223 * P2P Device configuration parameters.
