/*
* Notes:
*
* This driver is used to control the following SCSI adapters:
*
* IBM iSeries: 5702, 5703, 2780, 5709, 570A, 570B
*
* IBM pSeries: PCI-X Dual Channel Ultra 320 SCSI RAID Adapter

* - Supports attachment of non-RAID disks, tape, and optical devices
* - RAID Levels 0, 5, 10
* - Hot spare
* - Background Parity Checking
* - Background Data Scrubbing
* - Ability to increase the capacity of an existing RAID 5 disk array
* by adding disks
*
