James Smart | e59058c | 2008-08-24 21:49:00 -0400 | [diff] [blame] | 965 | * @phba: pointer to lpfc hba data structure. |
| 966 | * |
| 967 | * This is the actual HBA-timer timeout handler to be invoked by the worker |
| 968 | * thread whenever the HBA timer fired and HBA-timeout event posted. This |
| 969 | * handler performs any periodic operations needed for the device. If such |
| 970 | * periodic event has already been attended to either in the interrupt handler |
| 971 | * or by processing slow-ring or fast-ring events within the HBA-timer |
| 972 | * timeout window (LPFC_HB_MBOX_INTERVAL), this handler just simply resets |
| 973 | * the timer for the next timeout period. If lpfc heart-beat mailbox command |
| 974 | * is configured and there is no heart-beat mailbox command outstanding, a |
| 975 | * heart-beat mailbox is issued and timer set properly. Otherwise, if there |
| 976 | * has been a heart-beat mailbox command outstanding, the HBA shall be put |
| 977 | * to offline. |
