52fcf3ce44SJohn Forte  * Discovery Process
53fcf3ce44SJohn Forte  * =================
54fcf3ce44SJohn Forte  *
556e0414acSReed  *    The discovery process is a major function of FCP.	 In order to help
56fcf3ce44SJohn Forte  * understand that function a flow diagram is given here.  This diagram
57fcf3ce44SJohn Forte  * doesn't claim to cover all the cases and the events that can occur during
58fcf3ce44SJohn Forte  * the discovery process nor the subtleties of the code.  The code paths shown
59fcf3ce44SJohn Forte  * are simplified.  Its purpose is to help the reader (and potentially bug
60fcf3ce44SJohn Forte  * fixer) have an overall view of the logic of the code.  For that reason the
61fcf3ce44SJohn Forte  * diagram covers the simple case of the line coming up cleanly or of a new
62fcf3ce44SJohn Forte  * port attaching to FCP the link being up.  The reader must keep in mind
63fcf3ce44SJohn Forte  * that:
64fcf3ce44SJohn Forte  *
65fcf3ce44SJohn Forte  *	- There are special cases where bringing devices online and offline
66fcf3ce44SJohn Forte  *	  is driven by Ioctl.
67fcf3ce44SJohn Forte  *
68fcf3ce44SJohn Forte  *	- The behavior of the discovery process can be modified through the
69fcf3ce44SJohn Forte  *	  .conf file.
70fcf3ce44SJohn Forte  *
71fcf3ce44SJohn Forte  *	- The line can go down and come back up at any time during the
72fcf3ce44SJohn Forte  *	  discovery process which explains some of the complexity of the code.
