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
