352e5fd105 scsi: lpfc: Reinstate lpfc_soft_wwn parameter 
The lpfc 11.2.0.4 patch set deprecated, by removing, the lpfc_soft_wwn
parameter support.

This patch reinstates support, but adds a warning in the enablement of
the feature that indicates Broadcom (Emulex) does not support the
feature.

c691816e00 scsi: lpfc: Synchronize link speed with boot driver 
Synchronize link speed with boot driver

Link speed settings set by the boot driver are reported by the hw.
Driver will attempt to read them, and if set, will respect their
values.
The driver can override the settings with its own if instructed by
user space (via bsg), with the new values being picked up by the
boot driver.

c71ab8616d [SCSI] lpfc 8.3.36: Fixed boot from san failure 
Fixed boot from san failure when SLI4 FC device presented on the same PCI bus

The request_firmware interface can induce delays while looking
for firmware files, even if no fw file is present. In some situations
the delays exceeded scan_wait timeouts, resulting in situations in which
the boot device had not been discovered in time.  Boot Device does not
need to be on a lpfc device.

Change request_firmware use to be module paramater driven. Default is to
not attempt firmware download on boot. Add sysfs parameter to invoke
firmware update.
