70 * The Qlogic driver gets an interrupt to look at response queue entries.
71 * Some of these are status completions for initiatior mode commands, but
72 * if target mode is enabled, we get a whole wad of response queue entries
73 * to be handled here.
74 *
75 * Basically the split into 3 main groups: Lun Enable/Modification responses,
76 * SCSI Command processing, and Immediate Notification events.
77 *
78 * You start by writing a request queue entry to enable target mode (and
79 * establish some resource limitations which you can modify later).
80 * The f/w responds with a LUN ENABLE or LUN MODIFY response with
81 * the status of this action. If the enable was successful, you can expect...
82 *
83 * Response queue entries with SCSI commands encapsulate show up in an ATIO
84 * (Accept Target IO) type- sometimes with enough info to stop the command at
85 * this level. Ultimately the driver has to feed back to the f/w's request
86 * queue a sequence of CTIOs (continue target I/O) that describe data to
87 * be moved and/or status to be sent) and finally finishing with sending
88 * to the f/w's response queue an ATIO which then completes the handshake
89 * with the f/w for that command. There's a lot of variations on this theme,
90 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel
91 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic
92 * gist of it.
93 *
94 * The third group that can show up in the response queue are Immediate
95 * Notification events. These include things like notifications of SCSI bus
96 * resets, or Bus Device Reset messages or other messages received. This
97 * a classic oddbins area. It can get a little weird because you then turn
98 * around and acknowledge the Immediate Notify by writing an entry onto the
99 * request queue and then the f/w turns around and gives you an acknowledgement
100 * to *your* acknowledgement on the response queue (the idea being to let
101 * the f/w tell you when the event is *really* over I guess).
