	 * 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), ...)
