macroND6_LLINFO_INCOMPLETE

We don't need the WAITDELETE state any more, but we keep the definition in a comment line instead of removing it. This is necessary to avoid unintentionally reusing the value for another purpose, which might affect backward compatibility with old applications.

@function nd6_lookup_ipv6 @discussion This function will check the routing table for a cached neighbor discovery entry or trigger an neighbor discovery query to resolve the IPv6 address to a link-layer address. nd entries are stored in the routing table. This function will lookup the IPv6 destination in the routing table. If the destination requires forwarding to a gateway, the route of the gateway will be looked up. The route entry is inspected to determine if the link layer destination address is known. If unknown, neighbor discovery will be used to resolve the entry. @param interface The interface the packet is being sent on. @param ip6_dest The IPv6 destination of the packet. @param ll_dest On output, the link-layer destination. @param ll_dest_len The length of the buffer for ll_dest. @param hint Any routing hint passed down from the protocol. @param packet The packet being transmitted. @result May return an error such as EHOSTDOWN or ENETUNREACH. If this function returns EJUSTRETURN, the packet has been queued and will be sent when the address is resolved. If any other value is returned, the caller is responsible for disposing of the packet.
