When a ICMPV6_PKT_TOOBIG is received from a link local address the pmtu will
be updated on a route with an arbitrary interface index. Subsequent packets
sent back to the same link local address may therefore end up not
considering the updated pmtu.

When a ICMPV6_PKT_TOOBIG is received from a link local address the pmtu
will be updated on a route with an arbitrary interface index. Subsequent
packets sent back to the same link local address may therefore end up
not considering the updated pmtu.
