Details:

If a packet's destination address are same as netif that send this
packet(source address == destination address), 
ip_frag() dose not use netif_loop_output() to send this packet.

---------CODE---------
netif->output(netif, header, dest);
---------CODE---------

Should be replaced by:

---------CODE---------
#if (LWIP_NETIF_LOOPBACK || LWIP_HAVE_LOOPIF)
      if (ip_addr_cmp(dest, &netif->ip_addr)) {
        netif_loop_output(netif, p, dest);
      } else
#endif /* (LWIP_NETIF_LOOPBACK || LWIP_HAVE_LOOPIF) */
      {
        netif->output(netif, header, dest);
      }
---------CODE---------
