Public bug reported:

According to the design of IPv6 subnet ra mode and address mode, when
ipv6 address mode is None or SLAAC, VM either obtain address from
OpenStack/external RADVD or obtain address from external dhcp server.
It's not necessary to create DHCP port or spawn dnsmasq process for such
ipv6 subnets. Right now, the DHCP port is created and dnsmasq process is
spawned (but not used).

ra mode and address mode design:
