interrupt threads

[Orit Moskovich]

Hi,

I'm trying to understand the difference between using taskqueues defined by ithreads (taskqueue_swi, taskqueue_swi_giant, taskqueue_fast) to defer an interrupt's work, and defining an interrupt handler to give as ithread parameter to bus_setup_intr.
Is there a difference in the priority? Which of the methods is preferable when writing a network device and performance is important?

Thanks,
