Getting the values is currently supported and I reworked the transmit
power _setting_ in the at86rf230 driver. These steps are necessary to
support the transmit power setting. Varka Bhadram had support the
_setting_ of transmit power before [0]. He need to rebase his work and
change to mbm value handling, also he need to update the wpan-tools but
then it should work.


Varka are you already working on this? It's okay to make this now over
the NL802154_CMD_SET_TX_POWER cmd.

Thanks for this output it shows me an issue with the cca_ed_levels and
the at86rf212 transceiver.
