> This has an small hidden gotcha.  Since the macvlan device is moved
> completely into a container's network namespace, the init netns cannot
> freeze traffic to and from it in order to migrate live network connections
> by simply utilizing its netfilter tables.  A helper process in the container
> or something like what was recently discussed on the containers list[1]
> would provide a way to do this.
