I already told Martin that these patches should be based on bluetooth
(better bluetooth-next, 802.15.4 hasn't a real stable strategie and there
are also some known other issues in the current implementation). I don't
think that the current implementation is used in a real environment.

I get this patch-series in a resend of this series, after Martin
subscribed the linux-zigbee-devel mailinglist, then I told Martin that I
need some time for review and he want to resend them tomorrow or friday.
The resend should based on bluetooth-next then, if this is okay for you.

I will cc bluetooth mailinglist in my review notes.
