+       @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.
