| Subject: [PATCH] scsi: qla2xxx: Send Notify ACK after N2N PLOGI |
| |
| commit 5e6b01d84b9d20bcd77fc7c4733a2a4149bf220a upstream. |
| |
| 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. |
| |
