Isn't "link-local" supposed to mean that the address is unique and available only on that interface (ethernet segment)? It's possible to get the _same_ link-local address on multiple ethernet segments, so in that case, where would you send the packet??? When you send link-local packets, you must specify the link to which it is local.
