Title: Strict checking for link-local address

RFC 4291 requires that link-local addresses are within fe80::/64 even if the
link-local prefix is fe80::/10.

RFC 4291 IP Version 6 Addressing Architecture
2.5.6. Link-Local IPv6 Unicast Addresses

Link-Local addresses are for use on a single link. Link-Local
addresses have the following format:

| 10 |
| bits | 54 bits | 64 bits |
+----------+-------------------------+----------------------------+
|1111111010| 0 | interface ID |
+----------+-------------------------+----------------------------+
