727 | * or by processing slow-ring or fast-ring events within the HBA-timer | |
728 | * timeout window (LPFC_HB_MBOX_INTERVAL), this handler just simply resets | |
729 | * the timer for the next timeout period. If lpfc heart-beat mailbox command | |
730 | * is configured and there is no heart-beat mailbox command outstanding, a | |
731 | * heart-beat mailbox is issued and timer set properly. Otherwise, if there | |
732 | * has been a heart-beat mailbox command outstanding, the HBA shall be put | |
733 | * to offline. | |
