Subject: [PATCH v2 06/15] lpfc: Fix FW reset action if IOs are outstanding
Date: Mon,  4 Jan 2021 10:02:31 -0800	[thread overview]
Message-ID: <20210104180240.46824-7-jsmart2021@gmail.com> (raw)
In-Reply-To: <20210104180240.46824-1-jsmart2021@gmail.com>

If the port is configured for NVME and has any outstanding IOs when a FW
reset is requesteed, outstanding I/O's are not properly cleaned up. This
causes the fw download request to fail.

Fix by clearing the LPFC_SLI_ACTIVE flag to signify the I/O must be
manually flushed by the driver on port reset.
