Subject: [PATCH v3 05/13] scsi: qla2xxx: Change discovery state before PLOGI
Date: Mon, 25 Nov 2019 16:56:54 +0000	[thread overview]
Message-ID: <20191125165702.1013-6-r.bolshakov@yadro.com> (raw)
In-Reply-To: <20191125165702.1013-1-r.bolshakov@yadro.com>

When a port sends PLOGI, discovery state should be changed to login
pending, otherwise RELOGIN_NEEDED bit is set in
qla24xx_handle_plogi_done_event(). RELOGIN_NEEDED triggers another
PLOGI, and it never goes out of the loop until login timer expires.

Fixes: 8777e4314d397 ("scsi: qla2xxx: Migrate NVME N2N handling into state machine")
Fixes: 8b5292bcfcacf ("scsi: qla2xxx: Fix Relogin to prevent modifying scan_state flag")
