I haven't done any debugging of this yet - but if I did,
I would start by putting a break-point of some kind in udevd,
then adding an address.
What I would be looking for is if the adding of an address
generates a 'udev event' similar to discovering a new card.
I don't think it should, but it might be doing that.
It could also just be funky scripting somewhere.
