+# Example command line for the DPDK test-pmd application. Out of the 3 application cores (see the
+# -c <core_mask> argument), core 0 is running the master thread doing configuration and CLI, core 1
+# is running the forwarding thread, and core 2 is setup as service core (see the -s <core_mask>
+# argument) for the purpose of running the Soft NIC device:

+# 	testpmd> set portlist <softnic_port_id>
+#	testpmd> show config fwd
+#	testpmd> start

+# To setup the CLI prompt to the Soft NIC device, the DPDK test-pmd application needs to be modified
+# to call the rte_pmd_softnic_manage() function. Once the Soft NIC device is started, the command to
