91 * - All ethernet devices are not probed
92 * - "ethaddr" for all ethernet devices are not set
93 * - "ethact" is set to a valid ethernet device name
95 * With Sandbox default test configuration, all ethernet devices are
96 * probed after power-up, so we have to manually create such scenario:
97 * - Remove all ethernet devices
98 * - Remove all "ethaddr" environment variables
99 * - Set "ethact" to the first ethernet device
101 * Do a ping test to see if anything goes wrong.
