They use those SAP-commands (MCPS-SAP and MLME-SAP) which are described by 802.15.4 spec... there is this cfg802154_ops structure which will redirect netlink to either SoftMAC or HardMAC it should somehow conform to this... However I think it should be the minimum functionality inside of this, there might be a lot of optional things which only SoftMAC supports. Also nl802154 should be oriented to this. Are you agreeing here? - Alex
