19 `Wikipedia article on promiscuous mode
22 The network promiscuous APIs are used to enable and disable this mode,
23 and to wait for and receive a network data to arrive. Not all network
24 technologies or network device drivers support promiscuous mode.
29 First the promiscuous mode needs to be turned ON by the application like this:
