Vsock is just a L2 (and above) protocol from the view of the device. So
I think we should answer the question why we need two different paths
for networking traffic? Or what is the fundamental reason that makes
vsock does not go for virtio-net?

I agree they could be different type of devices but codes could be
shared in both guest and host (or even qemu) for not duplicating
features(bugs).

Thanks
