Subject: [PATCH 10/15] scsi: qla2xxx: Send Notify ACK after N2N PLOGI
References: bsc#1157424, bsc#1157908, bsc#1157169, bsc#1151548
Git-commit: 5e6b01d84b9d20bcd77fc7c4733a2a4149bf220a
Patch-mainline: v5.5 or v5.5-rc2 (next release)
qlt_handle_login schedules session for deletion even if a login is in
progress. That causes login bouncing, i.e. a few logins are made before
it settles down.
Complete the first login by sending Notify Acknowledge IOCB via
qlt_plogi_ack_unref if the session is pending login completion.
Fixes: 9cd883f07a54 ("scsi: qla2xxx: Fix session cleanup for N2N")
