receive_raw() builds an empty vnet header, if necessary. It is used to
send a gratuitous ARP reply from inside QEMU.
In the case where the NIC and its peer use vnet headers, packets
generated by QEMU internally cannot use ->receive() since they don't
know how to use the vnet header. ->receive_raw() takes care of that.
