If the enable was successful, you can expect... 79 * 80 * Response queue entries with SCSI commands encapsulate show up in an ATIO 81 * (Accept Target IO) type- sometimes with enough info to stop the command at 82 * this level. Ultimately the driver has to feed back to the f/w's request 83 * queue a sequence of CTIOs (continue target I/O) that describe data to 84 * be moved and/or status to be sent) and finally finishing with sending 85 * to the f/w's response queue an ATIO which then completes the handshake 86 * with the f/w for that command. There's a lot of variations on this theme, 87 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel 88 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic 89 * gist of it. 90 * 91 * The third group that can show up in the response queue are Immediate 92 * Notification events. These include things like notifications of SCSI bus 93 * resets, or Bus Device Reset messages or other messages received. This 94 * a classic oddbins area. It can get a little weird because you then turn 95 * around and acknowledge the Immediate Notify by writing an entry onto the 96 * request queue and then the f/w turns around and gives you an acknowledgement 97 * to *your* acknowledgement on the response queue (the idea being to let 98 * the f/w tell you when the event is *really* over I guess). 99 * 100 */ 101 102 103/* 104 * A new response queue entry has arrived.
