ieee802154: Add support for user beaconing requests
Parse user requests for sending beacons, start sending beacons at a
regular pace. If needed, the pace can be updated with a new request. The
process can also be interrupted at any moment.
The page and channel must be changed beforehands if needed. Interval
orders above 14 are reserved to tell a device it must answer BEACON_REQ
coming from another device as part of an active scan procedure and this
is not yet supported.
A netlink "beacon request" structure is created to list the
requirements.
Mac layers may now implement the ->send_beacons() and
->stop_beacons() hooks.
