+Usage
+=====
+
+Deploy the yaml
+
+```shell
+kubectl create namespace testpmd
+kubectl apply -f test.yaml
+```
+
+Start testpmd (4-6 being the CPU range on which to run testpmd)
+```shell
+kubectl -n testpmd exec -it testpmd memif-testpmd 4-6
+```
+
+The annotation in the yaml specification of the pod specifies that
+packets to the PodIP destined to ports between 4444 and 20000 for
+both TCP and UDP will be sent to the memif, and end up in testpmd.
+```yaml
+  annotations:
+    "cni.projectcalico.org/vppExtraMemifPorts": "tcp:4444-20000,udp:4444-20000"
+```
+
+Testpmd is started in 5tuple swap mode, meaning it will mirror all the packets
+it receives. In order to test it, either send a single TCP packet, e.g.
+`curl http://<testPmdPodIP>:4444` from another container or a cluster node.
+
+Alternatively you can also use a traffic generator like trex (see the corresponding 
+yaml under [../trex](../trex))
