58da1ffb2b [SCSI] lpfc 8.2.6 : Multiple discovery fixes
Multiple Discovery Fixes:
- Fix race on discovery due to link events coinciding with vport_delete.
- Use NLP_FABRIC state to filter out switch-based pseudo initiators that
   reuse the same WWNs.
- Correct erroneous setting of DID=0 in lpfc_matchdid()
- Correct extra reference count that was in the lookup path for the
  remoteid from an unsolicited ELS.
- Correct double-free bug in els abort path.
- Correct FDMI server discovery logic for switch that return a WWN of 0.
- Fix bugs in ndlp mgmt when a node changes address
- Correct bug that did not delete RSCNs for vports upon link transitions
- Fix "0216 Link event during NS query" error which pops up when vports
  are swapped to different switch ports.
- Add sanity checks on ndlp structures
- Fix devloss log message to dump WWN correctly
- Hold off mgmt commands that were interferring with discovery mailbox cmds
- Remove unnecessary FC_ESTABLISH_LINK logic.
- Correct some race conditions in the worker thread, resulting in devloss:
  - Clear the work_port_events field before handling the work port events
  - Clear the deferred ring event before handling a deferred ring event
  - Hold the hba lock when waking up the work thread
  - Send an acc for the rscn even when we aren't going to handle it
- Fix locking behavior that was not properly protecting the ACTIVE flag,
  thus allowing mailbox command order to shift.

ff86ba59fb [SCSI] lpfc: lpfc_debugfs.c: fix typo
This patch fixes a typo introduced by
commit bbfbbbc118.

It wasn't a compile error since CONFIG_LPFC_DEBUG_FS is not (yet?)
available as an option.

e8b62011d8 [SCSI] lpfc 8.2.2 : Rework the lpfc_printf_log() macro
Rework the lpfc_printf_log() macro so that logging is enabled on a
per-vport basis. Used to be on a physical-port basis, thus logging
with large numbers of vports became a mess.  Required redefinition of
the macro, and an update of every use.
