Subject: [PATCH wpan-next v4 01/11] ieee802154: Let PAN IDs be reset

Soon association and disassociation will be implemented, which will
require to be able to either change the PAN ID from 0xFFFF to a real
value when association succeeded, or to reset the PAN ID to 0xFFFF upon
disassociation. Let's allow to do that manually for now.
