Details:

Static route table management in LwIP.
    
APIs are:
1) s8_t ip6_add_route_entry (struct ip6_prefix *ip6_prefix,
                                             struct netif *netif,
                                             ip6_addr_t *gateway);
    
2) err_t ip6_remove_route_entry (struct ip6_prefix *ip6_prefix);
    
3) s8_t ip6_find_route_entry (ip6_addr_t *ip6_dest_addr);
    
4) struct netif *ip6_static_route(ip6_addr_t *src, ip6_addr_t *dest);
    
5)ip6_addr_t *ip6_get_gateway(struct netif *netif, ip6_addr_t *dest);
    
   -When adding a route entry, if a gateway is passed, then it would be
     added to the default router list with the neighbor cache netif entry
     pointing to the netif passed.
    
   -With this, a prefix match up to a specific prefix byte
     boundary would be made possible while doing a longest prefix match
     upon route lookup.
    
   -APIs 4 and 5 would be used for assigning to LWIP_HOOK_IP6_ROUTE and
     LWIP_HOOK_ETHIP6_GET_GW hooks.
