Most of net devices don't use interrupt threaded handler, looks we need to copy that first, :-) $git grep -n request_threaded_irq drivers/net/ | wc -l 9 $git grep -n request_threaded_irq drivers/net/wireless | wc -l 5 Also 5 of 9 using interrupt threaded handler are wireless network devices, which are a bit slow, and only one ethernet driver uses it. So I plan to use tasklet first, then we can switch to interrupt threaded handler in the future if mass storage devices are OK with it. If no one objects to use tasklet, I will post out the v1 patch for review later.
