With ip6tables enabled (by default), the daemon should start on a
host with IPv6 disabled - then error if IPv6 network creation is
attempted.
That regressed in commit 255fff4 - so, only try to set up network
isolation rules for a network if it's IPv6-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.
