2212* Notes:
2213* This task always run in the context of a kernel thread. It
2214* is kick-off by the driver's detect code and starts up
2215* up one per adapter. It immediately goes to sleep and waits for
2216* some fibre event. When either the interrupt handler or
2217* the timer routine detects a event it will one of the task
2218* bits then wake us up.
