Two reasons:

        (a) to allow both interface IDs and link IDs to be used to
            identify the zone of a link-local address (for backwards
            compatibility with current practice).

        (b) for use in in6_pktinfo.ipi6_ifindex, to restrict the set
            of outgoing interfaces to a zone less than that implied
            by the destination address.
