Hello Ivan:
      I found a bug the function tcpip_input(). This function forget to handle
IPv6. I has change it as follow. In the thread tcpip_thread(), it is handled
as this. 
err_t
tcpip_input(struct pbuf *p, struct netif *inp)
{
#if LWIP_TCPIP_CORE_LOCKING_INPUT
  err_t ret;
  LWIP_DEBUGF(TCPIP_DEBUG, ("tcpip_input: PACKET %p/%p\n", (void *)p, (void
*)inp));
  LOCK_TCPIP_CORE();
#if LWIP_ETHERNET
  if (inp->flags & (NETIF_FLAG_ETHARP | NETIF_FLAG_ETHERNET)) {
    ret = ethernet_input(p, inp);
  } else
#endif /* LWIP_ETHERNET */
#if LWIP_IPV6
   if ((*((unsigned char *)(p->payload)) & 0xf0) == 0x60) {
      ret = ip6_input(p, inp);
   } else
#endif /* LWIP_IPV6 */
   {
      ret = ip_input(p, inp);
   }
  UNLOCK_TCPIP_CORE();
  return ret;
#else /* LWIP_TCPIP_CORE_LOCKING_INPUT */
