AFAICR there is also some dual packet handling code path for XDP in
vhost_net/tun. I'm also willing to take the paper-cut, for cleaning

When you say dual packet handling, what are you referring to specifically?
The important part of the sentence was *code path*, as in multiple code
path for packets.
You tricked me into looking up the code for you...
It was in drivers/net/virtio_net.c where function receive_buf() calls[1]
three different functions based on different checks. Some cases support
XDP and others don't. I though you talked about this in another thread?
