Change Emulex HBA `lpfc_lun_queue_depth` parameter on the fly

Issue

• In order to manage and change settings on the fly, I have increased the lun_queue_depth on the Emulex HBA. Followed instructions as to how to manage the lun_queue_depth from an Operating System perspective by managing the options in /etc/modprobe.d/lpfc.conf file.
  However, I am unable to change parameters 'on the fly' and have to reboot for changes to take effect.
