Network interface cards (NICs) are programmed to only forward frames up to the operating system whose destination MAC address is either the MAC address of the NIC or the broadcast MAC address (ff:ff:ff:ff:ff:ff). To force the NIC to forward all messages up to the operating system, the card has to be put into what is called promiscuous mode. This just gets the NIC to forward all messages up, behaving promiscuously.
