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 para=
meter to bus_setup_intr.
Is there a difference in the priority? Which of the methods is preferable w=
hen writing a network device and performance is important?

Thanks,
Orit Moskovich
