[SCSI] lpfc 8.1.9 : Misc Bug Fixes
Misc Bug Fixes:
- Cap MBX_DOWN_LINK command timeout to 60 seconds
- Fix double free of ndlp object
- Don't free mbox structures on error. The completion handlers expect to do so.
- Clear host attention work items when going offline
- Fixed discovery issues in multi-initiator environments.
