register_allocator new protocol

[taegyo]

i attemp to add new protocol for capture goose packet. (tutorial part. 7)
but not recoginize pdu. / Windows 10 , 64bit

test code.
i used dummypdu template class on tutorial.

int main()
{
Allocators::register_allocator<EthernetII, DummyPDU>(0x88b8);

Packet packet;
NetworkInterface iface = NetworkInterface::default_interface();
Sniffer sniffer(iface.name());
while (1)
{
	packet = sniffer.next_packet();
	if (packet)
	{
		if (packet.pdu()->find_pdu<DummyPDU>())
		{
			const DummyPDU &dummy = packet.pdu()->rfind_pdu<DummyPDU>(); // non-const works as well
			std::string payload(dummy.get_buffer().begin(), dummy.get_buffer().end());
			std::cout << "Payload: " << payload << std::endl;
		}

	}
}

}
