/*
* linux/drivers/message/fusion/mptbase.c
- * High performance SCSI + LAN / Fibre Channel device drivers.
* This is the Fusion MPT base driver which supports multiple
* (SCSI + LAN) specialized protocol drivers.
- * For use with PCI chip/adapter(s):
- * LSIFC9xx/LSI409xx Fibre Channel
+ * For use with LSI Logic PCI chip/adapter(s)
* running LSI Logic Fusion MPT (Message Passing Technology) firmware.
*
- * Credits:
- * There are lots of people not mentioned below that deserve credit
- * and thanks but won't get it here - sorry in advance that you
- * got overlooked.
- *
- * This driver would not exist if not for Alan Cox's development
- * of the linux i2o driver.
- *
- * A special thanks to Noah Romer (LSI Logic) for tons of work
- * and tough debugging on the LAN driver, especially early on;-)
- * And to Roger Hickerson (LSI Logic) for tirelessly supporting
- * this driver project.
- *
- * A special thanks to Pamela Delaney (LSI Logic) for tons of work
- * and countless enhancements while adding support for the 1030
- * chip family. Pam has been instrumental in the development of
- * of the 2.xx.xx series fusion drivers, and her contributions are
- * far too numerous to hope to list in one place.
- *
- * All manner of help from Stephen Shirron (LSI Logic):
- * low-level FC analysis, debug + various fixes in FCxx firmware,
- * initial port to alpha platform, various driver code optimizations,
- * being a faithful sounding board on all sorts of issues & ideas,
- * etc.
- *
- * 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!
- *
- * Special thanks goes to the I2O LAN driver people at the
- * University of Helsinki, who, unbeknownst to them, provided
- * the inspiration and initial structure for this driver.
- *
- * A really huge debt of gratitude is owed to Eddie C. Dost
- * for gobs of hard work fixing and optimizing LAN code.
- * THANK YOU!
