There's a lot of variations on this theme, 84 * including flags you can set in the CTIO for the Qlogic 2X00 fibre channel 85 * cards that 'auto-replenish' the f/w's ATIO count, but this is the basic 86 * gist of it. 87 * 88 * The third group that can show up in the response queue are Immediate 89 * Notification events.
