[SCSI] lpfc 8.3.5: fix fcp command polling, add FIP mode, performance optimisations and devloss timout fixes
This patch includes the following changes: - Fixed Panic/Hang when using polling mode for fcp commands - Added support for Read_rev mbox bits indicating FIP mode of HBA - Optimize performance of slow-path handling of els responses - Add code to cleanup orphaned unsolicited receive sequences - Fixed Devloss timeout when multiple initiators are in same zone Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
