104 * receiving of EAPOL frames from an additional interface.

113 * interface that is not a network interface.

146 * wpa_debug_show_keys - Whether keying material is included in debug
148 * This parameter can be used to allow keying material to be included
149 * in debug messages. This is a security risk and this option should
150 * not be enabled in normal configuration. If needed during
