<p>I also added <code>NETCONF_OPT_CSMA_RETRIES</code> and to make clear that this is linked to <code>NETCONF_OPT_AUTOCCA</code> I figured that it should be renamed. Only the kw2xrf is using this option and this board also does CSMA. It's more precise and googling <code>AUTOCCA</code> only yields rubbish. <br>
But I see that renaming legacy options might not be a good idea per se.</p>
