Revision History:
+ Rev 3.27, February 10, 2009, Michael Reed
+ - General code cleanup.
+ - Improve error recovery.
Rev 3.26, January 16, 2006 Jes Sorensen
- Ditch all < 2.6 support
Rev 3.25.1, February 10, 2005 Christoph Hellwig
- Integrate ql12160_set_target_parameters() with 1280 version
- Make qla1280_setup() non static
- Do not call qla1280_check_for_dead_scsi_bus() on every I/O request
- sent to the card - this command pauses the firmare!!!
+ sent to the card - this command pauses the firmware!!!
Rev 3.23.15 Beta March 19, 2002, Jes Sorensen
- Clean up qla1280.h - remove obsolete QL_DEBUG_LEVEL_x definitions
- Remove a pile of pointless and confusing (srb_t **) and
