 *	- "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.
