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

109 * p2p_mgmt - Interface used for P2P management (P2P Device operations)
111 * Indicates whether wpas_p2p_init() must be called for this interface.
112 * This is used only when the driver supports a dedicated P2P Device
113 * interface that is not a network interface.

136 * will be written to the specified file.
141 * wpa_debug_level - Debugging verbosity level (e.g., MSG_INFO)
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
151 * development or while troubleshooting, this option can provide more
152 * details for figuring out what is happening.
