2078 * The plogi list and adisc list are used when Link Up discovery or RSCN
2079 * processing is needed. Each list holds the nodes that we will send PLOGI
2080 * or ADISC on. These lists will keep track of what nodes will be effected
2081 * by an RSCN, or a Link Up (Typically, all nodes are effected on Link Up).
2082 * The unmapped_list will contain all nodes that we have successfully logged
2083 * into at the Fibre Channel level. The mapped_list will contain all nodes
2084 * that are mapped FCP targets.
2087 * The bind list is a list of undiscovered (potentially non-existent) nodes
2088 * that we have saved binding information on. This information is used when
2089 * nodes transition from the unmapped to the mapped list.
2091 /* For UNUSED_NODE state, the node has just been allocated .
2092 * For PLOGI_ISSUE and REG_LOGIN_ISSUE, the node is on
2093 * the PLOGI list. For REG_LOGIN_COMPL, the node is taken off the PLOGI list
2094 * and put on the unmapped list. For ADISC processing, the node is taken off
2095 * the ADISC list and placed on either the mapped or unmapped list (depending
2096 * on its previous state). Once on the unmapped list, a PRLI is issued and the
2097 * state changed to PRLI_ISSUE. When the PRLI completion occurs, the state is
2098 * changed to UNMAPPED_NODE. If the completion indicates a mapped
2099 * node, the node is taken off the unmapped list. The binding list is checked
2100 * for a valid binding, or a binding is automatically assigned. If binding
2101 * assignment is unsuccessful, the node is left on the unmapped list. If
2102 * binding assignment is successful, the associated binding list entry (if
2103 * any) is removed, and the node is placed on the mapped list.
2106 * For a Link Down, all nodes on the ADISC, PLOGI, unmapped or mapped
2107 * lists will receive a DEVICE_RECOVERY event. If the linkdown or devloss timers
2108 * expire, all effected nodes will receive a DEVICE_RM event.
2111 * For a Link Up or RSCN, all nodes will move from the mapped / unmapped lists
2112 * to either the ADISC or PLOGI list. After a Nameserver query or ALPA loopmap
2113 * check, additional nodes may be added or removed (via DEVICE_RM) to / from
2114 * the PLOGI or ADISC lists. Once the PLOGI and ADISC lists are populated,
2115 * we will first process the ADISC list. 32 entries are processed initially and
2116 * ADISC is initited for each one. Completions / Events for each node are
2117 * funnelled thru the state machine. As each node finishes ADISC processing, it
2118 * starts ADISC for any nodes waiting for ADISC processing. If no nodes are
2119 * waiting, and the ADISC list count is identically 0, then we are done. For
2120 * Link Up discovery, since all nodes on the PLOGI list are UNREG_LOGIN'ed, we
2121 * can issue a CLEAR_LA and reenable Link Events. Next we will process the PLOGI
2122 * list. 32 entries are processed initially and PLOGI is initited for each one.
2123 * Completions / Events for each node are funnelled thru the state machine. As
2124 * each node finishes PLOGI processing, it starts PLOGI for any nodes waiting
2125 * for PLOGI processing. If no nodes are waiting, and the PLOGI list count is
2126 * indentically 0, then we are done. We have now completed discovery / RSCN
2127 * handling. Upon completion, ALL nodes should be on either the mapped or
