[SCSI] lpfc 8.3.25: Add FCF priority failover functionality
This patch implements a new FCF failover policy for the lpfc driver. It allows the driver to choose which FCF to failover to based on the FCF priority. This patch also introduces a new sysfs parameter (fcf_failover_policy) to allow the user to choose which FCF failover policy to use.
