Subject: [PATCH AUTOSEL 5.17 23/43] scsi: lpfc: Allow reduced polling rate for nvme_admin_async_event cmd completion
Date: Mon, 13 Jun 2022 22:05:42 -0400	[thread overview]
Message-ID: <20220614020602.1098943-23-sashal@kernel.org> (raw)
In-Reply-To: <20220614020602.1098943-1-sashal@kernel.org>

From: James Smart <jsmart2021@gmail.com>

[ Upstream commit 2e7e9c0c1ec05f18d320ecc8a31eec59d2af1af9 ]

NVMe Asynchronous Event Request commands have no command timeout value per
specifications.

Set WQE option to allow a reduced FLUSH polling rate for I/O error
detection specifically for nvme_admin_async_event commands.
