   4 Subject: [PATCH] hostapd: Add possibility to send debug messages to syslog
   5
   6 We can only send module specific messages to syslog and not debug
   7 messages printed with wpa_printf. Add an extra command line parameter
   8 '-s' to allow it. The feature is enabled with compile flag
   9 CONFIG_DEBUG_SYSLOG as for wpa_supplicant and behaves in the same manner
  10 as the wpa_supplicant -s command line argument.
