The general approach perhaps, but the rollover timing is way, way too 
aggressive IMO. It should be on a timer, not driven by PHY wake events. 
Even 300 seconds would be an improvement over the behaviour we're seeing.

As to "we need to learn to cope" - lots of networks have huge amounts of 
capital investment which can't just be ripped out and replaced overnight 
because Apple have decided to be aggressive with address rollovers. If 
the main outcome is for FIB-pressured sites to disable IPv6 on OUIs 
registered to Apple, it's a retrograde step ;o)

Maybe we need a "neigbour un-advert" ICMPv6 message that the old 
addresses could be torn down with.
