Hmnn... if its a question then it probably shouldn't go in the bug system until it is clear that it is a bug. There's nothing in a question that an engineer can fix.
Bug reports need to be roughly of the form. I did this, this is what I expected to happen, this is what actually happened. That makes it much more clear whether the observed behaviour is a bug or not.
So regarding MAC address, can you describe how you tried to lookup the MAC address. In this particular case (looking up a MAC address in Android GUI) there have been at least four different ways to lookup the MAC address over the years. Perhaps you are just using an out of date technique... (I'm afraid I can't just answer right now, I'm travelling and don't have my board plugged in at the moment).
