> Since this behaviour could be of interest for other MAC-protocols and is hidden "hidden" in HW in this Atmel device, we should maybe document that somewhere in the driver. I think e.g. Contiki-MAC would expect a min BE value of 0 to avoid any delays before sending.

That's actually a very good point. I wasn't aware that the random backoff wait is already active before the first attempt to transmitting. As I'm aiming for a MAC layer is even more important to me.

So in the first step it would be ok for **me** to have minBE=0 as a default, but I guess this should be configurable somehow. While going through all the interfaces involved, I still fail to find a good place for this, as it's really hardware specific and maybe not well placed as a NETCONF option.

What do you say?
