Comment 4 for bug 1625579

I still don’t see anything about any form of that parameter in the REST API docs anymore (http://developer.openstack.org/api-ref/networking/v2/?expanded=create-port-detail), but assuming it's still a real name, network code still uses the original resource module and not resource2, so to solve this you’ll probably have to override openstack.resource.Resource.create for in the openstack.network.v2.port.Port resource in order to make sure it only sends one (and the correct) name.

There's a change underway to shift network to use resource2, where this would not be a problem, but if you need this immediately it's easiest to just do that override as network will be a large transition to make.
