Sending raw frames (PF_PACKET) to a host-ap device?

[Pedro Estrela]

the best way to do this and a lot more, is to use the libpcap packet
capture/generation library that tcpdump uses.
using this library, you can most definitly:

- put a interface into promiscuous mode;
- receive all packets, with all headers up to level 2, including (later
versions of etheral pcap) prism2 headers;
- send any possible packets, including layer 2 headers. (for exemple, custum
ARP packets)

it's more complicated than a PF_packet socket, which also works, but its
MUCH more flexible.
