[SCSI] lpfc 8.3.6 : FC Protocol Fixes
FC protocol fixes.
- Fix send sequence logic to handle multi SGL IOCBs.
- Fix FDISC completion always setting VPORT state to failed.
- Ported the fix on reporting of max_vpi to uppper layer.
- Fix incorrect number of Vports allowed to be created.
- Fixed Dead FCoE port after creating vports.
- Added handling of ELS request for Reinstate Recovery Qualifier (RRQ)
- Handle unsolicited CT exchange initiator receiving CT exchange ABTS
- Migrate LUN queue depth ramp up code to scsi mid-layer.
- Made ABTS WQE go to the same WQ as the WQE to be aborted.
- Fix Vport does not rediscover after FCF goes away.
- Fixed lpfc_unreg_vfi failure after devloss timeout.
- Fixed RPI bit leak.
- Fix hbq pointer corruption during target discovery.
