   3  *      High performance SCSI / Fibre Channel SCSI Host device driver.
   4  *      For use with PCI chip/adapter(s):
   5  *          LSIFC9xx/LSI409xx Fibre Channel
   6  *      running LSI Logic Fusion MPT (Message Passing Technology) firmware.

   8  *  Credits:
   9  *      This driver would not exist if not for Alan Cox's development
  10  *      of the linux i2o driver.
  11  *
  12  *      A huge debt of gratitude is owed to David S. Miller (DaveM)
  13  *      for fixing much of the stupid and broken stuff in the early
  14  *      driver while porting to sparc64 platform.  THANK YOU!
