Metering and policing action typically sits on top of flow classification,
which is why MTR objects are enabled through a newly introduced flow
action.
The configuration of MTR objects is done in their own namespace (rte_mtr)
within the librte_ether library. The MTR object is hooked into ethdev RX
processing path using the "meter" flow action.

+Action: ``METER``
+^^^^^^^^^^^^^^^^^
+
+Applies a stage of metering and policing.
+
+The metering and policing (MTR) object has to be first created using the
+rte_mtr_create() API function. The ID of the MTR object is specified as
+action parameter. More than one flow can use the same MTR object through
+the meter action. The MTR object can be further updated or queried using
+the rte_mtr* API.
+
+- Non-terminating by default.
