James Smart 695a814e18 [SCSI] lpfc 8.3.8: BugFixes: Discovery relates changes
Discovery relates changes:
- Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and
  VPI_REGISTERED state so that driver can unregister physical port VPI
  independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI
  when physical port NportID change.
- Add code to unregister and re-register VPI of a vport when its Nport
  ID change.
- Add code in FDISC completion path to re-start FLOGI discovery when
  a FDISC complete with LOGIN_REQUIRED reason code.
- Fix a memory leak in lpfc_init_vpi_cmpl
- Add code to start a timer for vport to retry FDISC when CVL is received
  by a vport or physical port. If all Nports receive CVLs, then all timers
  are cancelled and a logical link level discovery will be started after
  one second.
- Flush ELS commands after killing all delayed ELS commands.

James Smart 3772a99175 [SCSI] lpfc 8.3.2 : Reorganization for SLI4
Preps the organization of the driver so that the bottom half, which
interacts with the hardware, can share common code sequences for
attachment, detachment, initialization, teardown, etc with new hardware.

For very common code sections, which become specific to the interface
type, the driver uses an indirect function call. The function is set at
initialization. For less common sections, such as initialization, the
driver looks at the interface type and calls the routines relative to
the interface.

8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space
