If a device sends packets with link-local addresses towards off-link
GUA addresses, such packets MUST be dropped.
Unfortunately, not all implementations do that - but not doing so is
a violation of one of the basic IPv6 RFCs.
(Also, forwarding LLA sourced packets off-link has no use case really -
where should the reply go to?)
