The gadget ethernet driver needs to keep copies of the MAC address (at both endpoints) as strings so it needs a custom function for validation of the MAC. It was not however performing a totally correct check and also was emitting a warning about a set but unused variable. The solution to both is that after checking the string contents we use the standard test for a valid MAC.
