52 * that case, ctrl_interface must be set to allow the interface to be
58 * ctrl_interface - Control interface parameter

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

118 * will be written to the specified file.
123 * wpa_debug_level - Debugging verbosity level (e.g., MSG_INFO)
128 * wpa_debug_show_keys - Whether keying material is included in debug
130 * This parameter can be used to allow keying material to be included
131 * in debug messages. This is a security risk and this option should
132 * not be enabled in normal configuration. If needed during
133 * development or while troubleshooting, this option can provide more
134 * details for figuring out what is happening.

164 * override_driver - Optional driver parameter override
166 * This parameter can be used to override the driver parameter in
167 * dynamic interface addition to force a specific driver wrapper to be
170 char *override_driver;
173 * override_ctrl_interface - Optional ctrl_interface override
175 * This parameter can be used to override the ctrl_interface parameter
176 * in dynamic interface addition to force a control interface to be
179 char *override_ctrl_interface;
182 * entropy_file - Optional entropy file
