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.
