[Openswan Users] kernel patch NAT TRAVERSAL

[vpn]

That's it, that code is not in net/ipv4/udp.c, the closest match is
      case 0:
      case UDP_ENCAP_ESPINUDP:
      case UDP_ENCAP_ESPINUDP_NON_IKE:
         up->encap_type = val;
         break;
      default:
         err = -ENOPROTOOPT;
         break;
      }
      break;
