Note that NAPI isn't just adaptive polling algorithm, but also splitting
interrupt work into to parts (hardware interrupt handler and softirq). This
might be big contributor to the win from using both in the same time as
well. 
I think that's the equivalent of fast and slow interrupts in bsd.  we basically (with some exceptions, like serial io) do all the work in the slow interrupt handler (= interrupt thread).
