     mfi - LSI Logic & Dell MegaRAID SAS RAID controller

     mfi* at pci? dev ? function ?

     The mfi driver provides support for the MegaRAID SAS family of RAID
     controllers, including:

           -   Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
           -   Intel RAID Controller SRCSAS18E, SRCSAS144E
           -   LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID
               SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP,
               MegaRAID SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP,
               MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS
           -   IBM ServeRAID M1015, ServeRAID M5014

     These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID
     50 and RAID 60 using either SAS or SATA II drives.

     Although the controllers are actual RAID controllers, the driver makes
     them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.

     mfi supports monitoring of the logical disks in the controller through
     the bioctl(8) and envstat(8) commands.

     The mfi driver is able to send events to powerd(8) if a logical drive in
     the controller is not online.  The state-changed event will be sent to
     the /etc/powerd/scripts/sensor_drive script when such condition happens.

     The mfi driver first appeared in NetBSD 4.0.
