+ * by an RSCN, or a Link Up (Typically, all nodes are effected on Link Up).
+ * The unmapped_list will contain all nodes that we have successfully logged

+ * that are mapped FCP targets.

+ * The bind list is a list of undiscovered (potentially non-existent) nodes

+ */
+/* For UNUSED_NODE state, the node has just been allocated .
+ * For PLOGI_ISSUE and REG_LOGIN_ISSUE, the node is on
+ * the PLOGI list. For REG_LOGIN_COMPL, the node is taken off the PLOGI list
+ * and put on the unmapped list. For ADISC processing, the node is taken off
+ * the ADISC list and placed on either the mapped or unmapped list (depending
+ * on its previous state). Once on the unmapped list, a PRLI is issued and the
+ * state changed to PRLI_ISSUE. When the PRLI completion occurs, the state is
+ * changed to UNMAPPED_NODE. If the completion indicates a mapped
+ * node, the node is taken off the unmapped list. The binding list is checked
+ * for a valid binding, or a binding is automatically assigned. If binding
+ * assignment is unsuccessful, the node is left on the unmapped list. If
+ * binding assignment is successful, the associated binding list entry (if
+ * any) is removed, and the node is placed on the mapped list.

+/*
+ * For a Link Down, all nodes on the ADISC, PLOGI, unmapped or mapped
+ * lists will receive a DEVICE_RECOVERY event. If the linkdown or nodev timers
+ * expire, all effected nodes will receive a DEVICE_RM event.
+ */
+/*
+ * For a Link Up or RSCN, all nodes will move from the mapped / unmapped lists
+ * to either the ADISC or PLOGI list. After a Nameserver query or ALPA loopmap
+ * check, additional nodes may be added or removed (via DEVICE_RM) to / from
+ * the PLOGI or ADISC lists. Once the PLOGI and ADISC lists are populated,
+ * we will first process the ADISC list. 32 entries are processed initially and
+ * ADISC is initited for each one. Completions / Events for each node are
+ * funnelled thru the state machine. As each node finishes ADISC processing, it
+ * starts ADISC for any nodes waiting for ADISC processing. If no nodes are
+ * waiting, and the ADISC list count is identically 0, then we are done. For
+ * Link Up discovery, since all nodes on the PLOGI list are UNREG_LOGIN'ed, we
+ * can issue a CLEAR_LA and reenable Link Events. Next we will process the PLOGI
+ * list. 32 entries are processed initially and PLOGI is initited for each one.
+ * Completions / Events for each node are funnelled thru the state machine. As

+ * indentically 0, then we are done. We have now completed discovery / RSCN
+ * handling. Upon completion, ALL nodes should be on either the mapped or
