2841* qla2x00_do_dpc
2842* This kernel thread is a task that is schedule by the interrupt handler
2843* to perform the background processing for interrupts.
2844*
2845* Notes:
2846* This task always run in the context of a kernel thread. It
2847* is kick-off by the driver's detect code and starts up
2848* up one per adapter. It immediately goes to sleep and waits for
2849* some fibre event. When either the interrupt handler or
2850* the timer routine detects a event it will one of the task
2851* bits then wake us up.
