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. | |
76 | * | |
77 | * Return codes | |

356 | * HBA to perform link configuration for the @vport; and the second mailbox | |

358 | * with the @vport. | |

9097 | * | |
9098 | * This routine is used as the top-level API for issuing a fabric iocb command | |
9099 | * such as FLOGI and FDISC. To accommodate certain switch fabric, this driver | |
9100 | * function makes sure that only one fabric bound iocb will be outstanding at | |
9101 | * any given time. As such, this function will first check to see whether there | |
9102 | * is already an outstanding fabric iocb on the wire. If so, it will put the | |
9103 | * newly issued iocb onto the driver internal fabric iocb list, waiting to be | |
9104 | * issued later. Otherwise, it will issue the iocb on the wire and update the | |
9105 | * fabric iocb count it indicate that there is one fabric iocb on the wire. | |
9106 | * | |
9107 | * Note, this implementation has a potential sending out fabric IOCBs out of | |
9108 | * order. The problem is caused by the construction of the "ready" boolen does | |
9109 | * not include the condition that the internal fabric IOCB list is empty. As | |
9110 | * such, it is possible a fabric IOCB issued by this routine might be "jump" | |
9111 | * ahead of the fabric IOCBs in the internal list. | |
9112 | * | |
9113 | * Return code | |
9114 | * IOCB_SUCCESS - either fabric iocb put on the list or issued successfully | |
