I heard of people running many hundreds of ppp interfaces on a single box acting as a DSL concentrator. They state to already have trouble handling the amount of uevents generated on such boxes just for the "add/remove" events of all the interfaces if something goes wrong with the network. If we add more for state transitions, such events would probably need to be rate-limited. In general, uevents/udev are not really suitable for high-frequency events, and if such behavior can be expected, we might better stick with the current netlink interface.
