+Generic flow API - examples
+===========================
+
+This document function is to supply some concrete examples for programming
+flow rules.
+
+* Detail API can be found in the following link: :ref:`Generic flow API <Generic_flow_API>` .
+
+* Detail TestPMD command to set the flow rules can be found in the
+  following link: :ref:`TestPMD Flow rules <testpmd_rte_flow>`

+
+In this example we will create a simple rule that drops packets that their IPv4

+mask.

+This code implements the following testpmd command::
