v1.1.1 2015-03-26
 * Support 4Kn drive.
 * Change the SCSI target ID of the disk to be the index of physical
   connetion to the HBA.
 * Support staggered drive spin up.
 * Fix a bug that command would be timeout because of improper
   interrupt service routine.
 * Error handling to avoid scsi command lost which caused system
   hang up.
