Detailed stats collection feature
Use device-input and interface-output feautre arcs to collect unicast, multicast
and broadcast states for RX and TX resp. Since these feature arcs are present only
for 'physical' interfaces (i.e. not su-interfaces) counter collection is supported
only on parent interface types.
