mac802154: Handle association requests from peers
Coordinators may have to handle association requests from peers which
want to join the PAN. The logic involves:
- Acknowledging the request (done by hardware)
- If requested, a random short address that is free on this PAN should
be chosen for the device.
- Sending an association response with the short address allocated for
the peer and expecting it to be ack'ed.
If anything fails during this procedure, the peer is considered not
associated.
