Subject: [PATCH v2 06/14] qla2xxx: Fix N2N link up fail
Date: Thu, 12 Sep 2019 11:09:10 -0700	[thread overview]
Message-ID: <20190912180918.6436-7-hmadhani@marvell.com> (raw)
In-Reply-To: <20190912180918.6436-1-hmadhani@marvell.com>

From: Quinn Tran <qutran@marvell.com>

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.
