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.
