* linux/drivers/message/fusion/mptscsih.h
* High performance SCSI / Fibre Channel SCSI Host device driver.

* 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!
