While netmap implements virtio-net header, it does not implement
receive_raw().

The only user for raw is the announcing. Netmap probably doesn't it at all.

In my understanding, the announcing *sends* a raw packet.


It's send via NIC and receive by its peer which is the TAP

qemu_send_packet_raw() -> nc -> nc->peer -> peer->receive_raw()?

Anything I miss?

The problem is that the peer can be netmap and netmap also requires a virtio-net header.
