Some devices, like hardMAC ones can be a bit limited in the way they handle mac commands. In particular, they might just not support it at all and instead only be able to transmit and receive regular data packets. In this case, they cannot be used for any of the internal management commands that we have introduced so far and must be flagged accordingly.
