Public bug reported:

This blueprint added support to nova for having multiple ports attached
to an instance on the same network:

https://blueprints.launchpad.net/nova/+spec/multiple-if-1-net

However, with the "Multinic" API extension in nova, if you're adding a
fixed_ip to an instance, the neutronv2 API will only copy the fixed_ips
from the first subnet on the network to the first port associated with
the instance:

https://github.com/openstack/nova/blob/2015.1.0b2/nova/network/neutronv2/api.py#L745

Once that's done, the code returns and the other subnets/ports aren't
handled.
