Starting with v197, systemd uses predictable interface network names, the traditional interface naming scheme (eth0) is deprecated, therefore it cannot be assumed that the eth0 interface exists on the host. This modification makes the bind_bhash test program run in a separate network namespace and no longer needs to consider the name of the network interface on the host.
