Subject[PATCH AUTOSEL 4.18 017/131] scsi: qla2xxx: Fix session state stuck in Get Port DB
Date
From: Quinn Tran <quinn.tran@cavium.com>

[ Upstream commit 8fde6977ac478c00eeb2beccfdd4a6ad44219f6c ]

This patch sets discovery state back to GNL (Get Name List) when session is
stuck at GPDB (Get Port DataBase). This will allow state machine to retry
login and move session state ahead in discovery.
