Subject: scsi: qla2xxx: NVME|FCP prefer flag not being honored
From: Quinn Tran <qutran@xxxxxxxxxxx>
commit 69aecdd410106dc3a8f543a4f7ec6379b995b8d0 upstream.
Changing of [FCP|NVME] prefer flag in flash has no effect on driver. For
device that supports both FCP + NVMe over the same connection, driver
continues to connect to this device using the previous successful login
mode.
On completion of flash update, adapter will be reset. Driver will
reset the prefer flag based on setting from flash.
