54 * that case, ctrl_interface must be set to allow the interface to be
60 * confanother - Additional configuration name (file or profile) name

73 * set, ctrl_interface is used to override the value from configuration

86 * If a configuration file is not used, this variable can be used to

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

110 * p2p_mgmt - Interface used for P2P management (P2P Device operations)
112 * Indicates whether wpas_p2p_init() must be called for this interface.
113 * This is used only when the driver supports a dedicated P2P Device
114 * interface that is not a network interface.
120 * struct wpa_params - Parameters for wpa_supplicant_init()
124 * daemonize - Run %wpa_supplicant in the background
129 * wait_for_monitor - Wait for a monitor program before starting

137 * will be written to the specified file.
142 * wpa_debug_level - Debugging verbosity level (e.g., MSG_INFO)
147 * wpa_debug_show_keys - Whether keying material is included in debug
149 * This parameter can be used to allow keying material to be included
150 * in debug messages. This is a security risk and this option should
151 * not be enabled in normal configuration. If needed during
152 * development or while troubleshooting, this option can provide more
153 * details for figuring out what is happening.
