16  * debug level can be programmed on the fly via SysFS (hex values)

18  * Example: (programming for MPT_DEBUG_EVENTS on host 5)
19  *
20  * echo 8 > /sys/class/scsi_host/host5/debug_level
21  *
22  * --------------------------------------------------------
23  * mpt_debug_level - command line parameter
24  * this allow enabling debug at driver load time (for all iocs)
25  *
26  * Example (programming for MPT_DEBUG_EVENTS)
27  *
28  * insmod mptbase.ko mpt_debug_level=8
29  *
30  * --------------------------------------------------------
31  * CONFIG_FUSION_LOGGING - enables compiling debug into driver
32  * this can be enabled in the driver Makefile
33  *
34  *
35  * --------------------------------------------------------
36  * Please note most debug prints are set to logging priority = debug
37  * This is the lowest level, and most verbose. Please refer to manual
38  * pages for syslogd or syslogd-ng on how to configure this.
