I have modified (e.g. got rid of threads) the original patch from the forum and
am using it here on Windows. It works fine but performance is pretty low.

On Windows it should be -lwpcap.

+    if ((fd = pcap_get_selectable_fd(s->handle)) < 0) {
+ fprintf(stderr, "qemu: pcap_get_selectable_fd failed\n");
+ goto fail;
+    }
+    qemu_set_fd_handler(fd, pcap_send, NULL, s);

pcap_get_selectable_fd() is not available on Windows. I just put
pcap_send() in main_loop_wait().
