Subject[PATCH AUTOSEL 4.18 016/131] scsi: qla2xxx: Fix unintended Logout
Date
From: Quinn Tran <quinn.tran@cavium.com>

[ Upstream commit cb97f2c2e8d9f8c71ddbf04ad57e163ee6d86474 ]

During normal IO, FW can return IO with 'port unavailble' status. Driver
would send a LOGO to remote port for session resync. On an off chance, a
PLOGI could arrive before sending the LOGO. This patch will skip sendiing
LOGO if a PLOGI just came in.
