In NPIV environment, a NPIV host may use a queue pair created by base host
or other NPIVs, so the check for a queue pair created by this NPIV is not
correct, and can cause an abort to fail, which in turn means the NVME
command not returned.  This leads to hang in nvme_fc layer in
nvme_fc_delete_association() which waits for all I/Os to be returned, which
is seen as hang in the application.

commit e4e3a2ce ("scsi: qla2xxx: Add ability to autodetect SFP
type") takes a heavy handed approach to BPM (Buffer Plus Management)
enablement:

1) During hardware initialization, if an LR-capable transceiver is
   recognized, the driver schedules a disruptive post-initialization
   chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the
   firmware.  This chip-reset will result in (short-term) path-loss to
   all fc-rports and their attached SCSI devices.

2) LR-detection is triggered during any link-up event, resulting in a
   refresh and potential chip-reset

Based on firmware-team guidance, upon LR-capable transceiver
recognition, the driver's hardware initialization code will now
re-execute firmware with the new BPM settings, then continue on with
driver initialization.  To address the second issue, the driver
performs LR-capable detection upon the driver receiving a
transceiver-insertion asynchronous event from firmware.  No short-term
path loss is needed with this new semantic.

 - Displays (in hex) the LED config words for all three LEDs.

 - Programs the config words for one LED or for all three LEDs.

The sysfs node defined is named beacon_config.

First, to allow driver to gain LED control, do this:
 # echo 1 > /sys/class/scsi_host/host#/beacon

Then, to display config words for all three LEDs do this:
 # cat /sys/class/scsi_host/host#/beacon_config

To set config words for all three LEDs do this:
 # echo 3 xxxx yyyy zzzz > /sys/class/scsi_host/host#/beacon_config

Or, to set config word for a specific single LED n do this:
 # echo n xxxx > /sys/class/scsi_host/host#/beacon_config
  where n is the LED number (0, 1, 2)

Finally, to restore LED control back to firmware, do this:
 # echo 0 > /sys/class/scsi_host/host#/beacon
