These are warnings based on commit b96ced9cdb6 (sandbox: eth-raw: Make random MAC addresses available to eth-raw). Because we don't know the number of interfaces that exist on the given host when we write the sandbox.dts, we override the MAC addresses with random ones. In the normal case (real hardware), we would warn, since the hardware should know its interfaces. Do you have a proposed different approach? I don't like the idea of adding sandbox checks in the core code that prints this warning, and it also doesn't seem like a great idea to add a hook that doesn't warn just for sandbox. I'm happy to work on this, but I didn't address it at the time because I didn't see a clear way to do it that didn't degrade the code in order to remove warnings in sandbox.
