Subject: [PATCH v2 07/17] qla2xxx: add retry for exec fw
Date: Sun, 9 Jan 2022 21:02:08 -0800	[thread overview]
Message-ID: <20220110050218.3958-8-njavali@marvell.com> (raw)
In-Reply-To: <20220110050218.3958-1-njavali@marvell.com>

From: Quinn Tran <qutran@marvell.com>

Per FW request, Exec FW can fail due to temp error resulting in driver not
attaching to the adapter. Add retry of this command up to 4 retries.
