The only metadata that can be passed with tuntap, pf_packet et al is
virtio_net_hdr.

I quite don't understand where xen-netfront et al come in.

The problem is, what kind of issue you want to solve. If you want to
solve virtio specific issue, why do you need to do that in the general
flow dissector?

Suppose we determine that it would indeed also be good to add
support for xen-netfront, netvsc validation in this way. Is your
suggestion that these would need to be added all in the same patch
series?

No.

Could we not implement just virtio-net first, and add the
others subsequently, if we can demonstrate a feasible plan for
doing so? Thanks

Yes, as replied in another thread. I want to make sure whether doing 
this via flow dissector is the best way.

Thanks
