Nope. My understanding is that it's an ARP storm, or something similar,
when the iPhone roams onto a new 802.11 hotspot. Apple hasn't issued a
fix yet, so Cisco had to do an emergency patch for some of their larger
customers. This is just my understanding based on one conversation about
it. I'd feel like an idiot saying "don't quote me" on NANOG, but... I
don't have any special knowledge about it, nor personal experience of it,
so...
