Subject[PATCH AUTOSEL 5.3 13/68] scsi: qla2xxx: Fix N2N link up fail
Date
From: Quinn Tran <qutran@marvell.com>

[ Upstream commit f3f1938bb673b1b5ad182c4608f5f8a24921eea3 ]

During link up/bounce, qla driver would do command flush as part of
cleanup. In this case, the flush can intefere with FW state. This patch
allows FW to be in control of link up.
