/*
 * debug level can be programmed on the fly via SysFS (hex values)
 *
 * Example:  (programming for MPT_DEBUG_EVENTS on host 5)
 *
 * echo 8 > /sys/class/scsi_host/host5/debug_level
 *
 * --------------------------------------------------------
 * mpt_debug_level - command line parameter
 * this allow enabling debug at driver load time (for all iocs)
 *
 * Example  (programming for MPT_DEBUG_EVENTS)
 *
 * insmod mptbase.ko mpt_debug_level=8
 *
 * --------------------------------------------------------
 * CONFIG_FUSION_LOGGING - enables compiling debug into driver
 * this can be enabled in the driver Makefile
 *
 *
 * --------------------------------------------------------
 * Please note most debug prints are set to logging priority = debug
 * This is the lowest level, and most verbose.  Please refer to manual
 * pages for syslogd or syslogd-ng on how to configure this.
