e353546e44 [SCSI] bfa: Add diagnostic port (D-Port) support
- Introduced support for D-Port which is a new port mode during which
  link level diagnostics can be run.
- Provided mechanism to dynamically configure D-Port and initiate diagnostic
  tests to isolate any link level issues.
- In D-Port mode, the HBA port does not participate in fabric or login to the
  remote device or run data traffic.
- Diagnostic tests include running various loopback tests in conjunction with
  the attached device.

ee1a4a42f6 [SCSI] bfa: FCS remote port enhancements.
- Introduced rport qualifier structure and modified design to
  export remote ports with valid pid or valid pwwn to the user space.
- Introduced old_pid field in the rport structure and made changes to
  prevent re-creating a new remote port for an already existing rport
  that is transitioning to a delete state. (Happens if we receive a RSCN
  on the existing remote port that is getting deleted).
