main ideas are: * Separates the Contiki low-layer network stack into four layers: network (e.g. sicslowpan / rime), Medium Access Control MAC (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and radio (e.g. cc2420). * Introduces a new way to configure the network stack. Four #defines that specify what mechanism/protocol/driver to use at the four layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC, NETSTACK_CONF_RADIO. * Adds a callback mechanism to inform the MAC and network layers about the fate of a transmitted packet: if the packet was not possible to transmit, the cause of the failure is reported, and if the packets was successfully transmitted, the number of tries before it was finally transmitted is reported. * NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc, which can be used when MAC and RDC functionality is not needed. * Extends the radio API with three new functions that enable more efficient radio duty cycling protocols: channel check, pending packet, and receiving packet. * New initialization mechanism, which takes advantage of the NETSTACK #defines.
