    [SCSI] lpfc 8.2.5 : Miscellaneous discovery Fixes
    
    Miscellaneous discovery fixes:
    - Flush RSCN buffers on vports when reseting HBA.
    - Fix incorrect FLOGI after vport reg failed
    - Fix a potential fabric ELS race condition
    - Fix handling of failed PLOGI command under high lip rates
    - Fix FDISC handling
    - Fix debug logging for npiv handling
