for virtio-net upstream in qemu?

IIRC the current hacks are not upstream quality.

The problem (again IIRC) is that the guest and host negotiate a protocol, but the qemu vlan model doesn't have a guest and a host, it has peers (possibly more than two), so a lot of translation has to take place if you have one peer supporting a guest feature and another not.

IMO the best way out is to drop the vlan model. It has its uses, but they can all be implemented in other ways, and are all have minor usage compared to the business of getting data into and out of a guest.
