For swarm networks, Controller.NewNetwork is called to validate
network config ... nothing gets created, but ManagerRedirectError
is returned if the config is ok - then swarm does its own thing.
So, for a --config-from network, merge config before checking
whether it'll have IPv4 enabled.

Libnetwork provides a native Go implementation for connecting containers
The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.
There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
