Public bug reported:

The spec [1] points out how a subnet configured with ipv6 address mode dhcpv6-stateful and ra mode none should behave:
"VM obtains IPv6 address and optional info from dnsmasq using DHCPv6 stateful" [1]

Now creating such an subnet and adding it as routers interface resulted in the following error message:
neutron subnet-create --name subnet_ipv6-network --enable-dhcp --ip-version 6 --ipv6-address-mode dhcpv6-stateful ipv6-network 2003::/64
