Public bug reported: In the devstack environment (master branch), stack.sh created the private network. It has two subnets it (an IPv4 and an IPv6).
A port is created using the "private" network. Then the port is updated using the "openstack port set --no-fixed-ip" command. The IPv4 IP address is removed but not the IPv6 address. stack@dvstku1804:/etc/neutron$ openstack port show test-private-port
