Originally we implemented RFC 7217 for link-local addresses, too. The value of doing that is IMO not very high and it turned out that there are ISPs out there that calculate the clients link-local address from the MAC address and route a /64 (or whatever) to that link-local address. If we calculate a different link-local address IPv6 is broken. It's pretty difficult to debug this so we removed support for it in the kernel. p.s. Furthermore I think link-local addresses should be generated by userland. -- In my defence, I have been left unsupervised.
