+ *  linux/drivers/message/fusion/mptscsih.h
+ *      High performance SCSI / Fibre Channel SCSI Host device driver.
+ *      For use with PCI chip/adapter(s):
+ *          LSIFC9xx/LSI409xx Fibre Channel
+ *      running LSI Logic Fusion MPT (Message Passing Technology) firmware.
+ *
+ *  Credits:
+ *      This driver would not exist if not for Alan Cox's development
+ *      of the linux i2o driver.
+ *
+ *      A huge debt of gratitude is owed to David S. Miller (DaveM)
+ *      for fixing much of the stupid and broken stuff in the early
+ *      driver while porting to sparc64 platform.  THANK YOU!
+ *
