Docker-tc cannot update network interface after a container restarts

[DullJZ]

When I run a new container and add the label for limit, the docker-tc can find it and set the limit successfully.

However, after the container restarts, the network interface changes. For example, docker-tc sets limit on vethd104b6f. After restarting my container, it changed to vethffc7586. But docker-tc seems not to realize it, so the limit doesn't work.
