Hot plug is good and needed.
But it needs to be done in a generic fashion in the bus layer.
There is nothing about uevents that are unique to i40e or even Intel
devices. Plus the way hotplug is handled is OS specific, so this isn't going
to work well on BSD.
Sorry if I sound like a broken record but there has been a repeated pattern
of Intel developers putting their head down (or in the sand) and creating
functionality inside device driver.
