d7be54cc5c [SCSI] bfa: FCS bug fixes.
- Added logic to initiate a PLOGI to the target, while processing a LOGO
  from the same target in Direct attach mode.
- Added logic to generate a FCCT Reject indicating unsupported command,
  upon receiving FCCT/FCGS requests.
- Added logic to set the fcpim in offline state and avoid any PRLI retries
  if a PRLI response is a reject with a reason Command Not Supported.
- Updated the FDMI Supported/Current speeds.
- Added logic to wait for the response  from the firmware before sending
  ACC to PLOGI and transitioning to subsequent states - while processing an
  Incoming PLOGI in online state.
- Added a wait state in the fcs_vport state machine - For case where
  FDISC is in progress and we get a vport delete request we wait for
  fdisc response and will transition to the appropriate state based on
  rsp status, else its causing both driver/fw resources to be not
  freed.
- Remove the fc_credit_recovery module param.

be540a991e [SCSI] bfa: FC credit recovery and misc bug fixes.
- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.

Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
  timer calibration (around 300 miilisecs earlier). So there is a
  window if an accept comes during this time HBA would have initiated
  an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.

5fbe25c7a6 [SCSI] bfa: fix comments for c files
This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.
