62 | * This routine checks whether there is an outstanding host link | |

64 | * by reading the HBA's Host Attention (HA) register. If there is any host | |

66 | * shall be marked as FC_ABORT_DISCOVERY, a host link attention clear shall | |
67 | * be issued if the link state is not already in host link cleared state, | |
68 | * and a return code shall indicate whether the host link attention event | |
69 | * had happened. | |
70 | * | |
71 | * Note that, if either the host link is in state LPFC_LINK_DOWN or @vport | |
72 | * state in LPFC_VPORT_READY, the request for checking host link attention | |
73 | * event will be ignored and a return code shall indicate no host link | |
74 | * attention event had happened. | |
75 | * | |
76 | * Return codes | |
77 | * 0 - no host link attention event happened | |

3068 | * This routine makes a retry decision on an ELS command IOCB, which has | |
3069 | * failed. The following ELS IOCBs use this function for retrying the command | |
3070 | * when previously issued command responsed with error status: FLOGI, PLOGI, | |
3071 | * PRLI, ADISC, LOGO, and FDISC. Based on the ELS command type and the | |
3072 | * returned error status, it makes the decision whether a retry shall be | |
3073 | * issued for the command, and whether a retry shall be made immediately or | |
3074 | * delayed. In the former case, the corresponding ELS command issuing-function | |
3075 | * is called to retry the command. In the later case, the ELS command shall | |
3076 | * be posted to the ndlp delayed event and delayed function timer set to the | |
3077 | * ndlp for the delayed command issusing. | |
3078 | * | |
3079 | * Return code | |
3080 | * 0 - No retry of els command is made | |
3081 | * 1 - Immediate or delayed retry of els command is made | |
