+ * - "ethact" is set to a valid ethernet device name
+ *
+ * With Sandbox default test configuration, all ethernet devices are
+ * probed after power-up, so we have to manually create such scenario:
+ * - Remove all ethernet devices
+ * - Remove all "ethaddr" environment variables
+ * - Set "ethact" to the first ethernet device
+ *
+ * Do a ping test to see if anything goes wrong.
