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

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

3391 | * This routine makes a retry decision on an ELS command IOCB, which has | |
3392 | * failed. The following ELS IOCBs use this function for retrying the command | |
3393 | * when previously issued command responsed with error status: FLOGI, PLOGI, | |
3394 | * PRLI, ADISC, LOGO, and FDISC. Based on the ELS command type and the | |
3395 | * returned error status, it makes the decision whether a retry shall be | |
3396 | * issued for the command, and whether a retry shall be made immediately or | |
3397 | * delayed. In the former case, the corresponding ELS command issuing-function | |
3398 | * is called to retry the command. In the later case, the ELS command shall | |
3399 | * be posted to the ndlp delayed event and delayed function timer set to the | |
3400 | * ndlp for the delayed command issusing. | |
3401 | * | |
3402 | * Return code | |
3403 | * 0 - No retry of els command is made | |
3404 | * 1 - Immediate or delayed retry of els command is made | |

4095 | * field in the command IOCB is not NULL, the referred mailbox command will | |
4096 | * be send out, and then invokes the lpfc_els_free_iocb() routine to release | |
4097 | * the IOCB. Under error conditions, such as when a LS_RJT is returned or a | |
4098 | * link down event occurred during the discovery, the lpfc_nlp_not_used() | |
4099 | * routine shall be invoked trying to release the ndlp if no other threads | |
