+Subject: [PATCH] hostapd: Add possibility to send debug messages to syslog
+
+We can only send module specific messages to syslog and not debug
+messages printed with wpa_printf. Add an extra command line parameter
+'-s' to allow it. The feature is enabled with compile flag
+CONFIG_DEBUG_SYSLOG as for wpa_supplicant and behaves in the same manner
+as the wpa_supplicant -s command line argument.
