====================
pull-request: ieee802154 2017-09-20

Here comes a pull request for ieee802154 changes I have queued up for
this merge window.

Normally these have been coming through the bluetooth tree but as this
three have been falling through the cracks so far and I have to review
and ack all of them anyway I think it makes sense if I save the
bluetooth people some work and handle them directly.

Its the first pull request I send to you so please let me know if I did
something wrong or if you prefer a different format.
