4e51af9ee7 bfa: fix bfa_fcb_itnim_alloc() error handling
The caller assumes that "itnim" is NULL on error and non-NULL on success
but really "itnim" is uninitialized on error.  This function should just
use normal error handling where it returns zero on success and negative
on failure.

61ba43947e [SCSI] bfa: Add support for max target ports discovery
- Changes to avoid discovering NPIV port as remote port by the other
  NPIV ports created on same physical port when all the NPIV ports are
  part of the same zone in a fabric.
- Provided mechanism to support maximum number of target ports for a
  given initiator port (physical port + NPIV ports) irrespective of the
  way in which the initiator and target ports are zoned in the fabric.
- Introduced module_parameter max_rport_logins to restrict number of
  remote ports discovery which includes target and initiator remote ports.

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.

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 */.
