     * the VPN plugin, it maps those levels to syslog levels as follows:

     *

     *  LOGL_INFO = LOG_NOTICE,

     *  LOGL_DEBUG = LOG_INFO,

     *  LOGL_TRACE = LOG_DEBUG,

     * However, when actually printing to syslog, we don't want to print messages

     * with LOGL_INFO level as LOG_NOTICE, because they are *not* to be highlighted.

     *

     * In other words: NetworkManager has 3 levels that should not require highlighting:

     * LOGL_INFO, LOGL_DEBUG, LOGL_TRACE. syslog on the other hand has only LOG_INFO and LOG_DEBUG.

     *

     * So, coerce those values before printing to syslog. When you receive the syslog_level

     * from NetworkManager, instead of calling

     *   syslog(syslog_level, ...)

     * you should call

     *   syslog(nm_utils_syslog_coerce_from_nm(syslog_level), ...)
