[SCSI] lpfc 8.1.11 : Discovery Fixes
Discovery Fixes:
- Prevent starting discovery of a node if discovery is in progress.
- Code improvement (reduction) for lpfc_findnode_did().
- Update discovery to send RFF to Fabric on link up
- Bypass unique WWN checks for fabric addresses
- Add ndlp to plogi list prior to issuing the plogi els command
