Since nova-network has been deprecated, all of our networking work for Hyper-V is concentrated on Neutron. The Nova driver supports flat networking (static and dhcp), but if need VLANs, L3 and other more advanced features Neutron becomes a requirement.
This is unclear - does OpenStack on Hyper-V support nova-networking (non neutron) or not? Nova-network is in fact still being updated, even for Juno, due to Neutron's continued lack of feature parity.
