Subject[PATCH 5.4 63/80] scsi: qla2xxx: Change discovery state before PLOGI
Date
From: Roman Bolshakov <r.bolshakov@yadro.com>

commit 58e39a2ce4be08162c0368030cdc405f7fd849aa upstream.

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")
