net: ieee802154: Handle limited devices with only datagram support
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.
