Detailed Description

A network request to only a single destination.

A Virtio_net_request can have multiple destinations (being a broadcast request, for example). That is why it is processed by multiple Virtio_net_transfers, each representing the delivery to a single destination port.

Virtio_port::handle_request uses the transfer function to move one packet to the destination of the request.
