Packet Reading for Network Emulation
... In promiscuous mode no hardware filtering is done and the card passes on all packets that it sees to the host kernel. The kernel is then free to filter and discard packets as it sees fit. This filtering is being performed in software, which is slower but more flexible. Promiscuous mode is generally ...
