Public bug reported:

When call driver enable is called. the cleanup_stale_devices function is invoked to remove stale devices
within the namespace. The method cleanup_stale_devices examines the
ports in the network to	prevent the unintentional removal of
legitimate devices.

In a multisegment context, the initial device created might be deleted
during the second iteration. This occurs because the network variable
used in the loop is not a singular reference to the same object,
resulting in its ports not being updated by the ones created during
previous iterations.
