 The initial implementation of NFV service density tests in
 |csit-release| is using two NF applications:
 
-- VNF: DPDK L3fwd running in KVM VM, configured with /8 IPv4 prefix
-  routing. L3fwd got chosen as a lightweight fast IPv4 VNF application,
-  and follows CSIT approach of using DPDK sample applications in VMs for
-  performance testing.
-- CNF: VPP running in Docker Container, configured with /24 IPv4 prefix
-  routing. VPP got chosen as a fast IPv4 NF application that supports
-  required memif interface (L3fwd does not). This is similar to all
-  other Container tests in CSIT that use VPP.
+- VNF: VPP of the same version as vswitch running in KVM VM, configured with /8

 Tests are designed such that in all tested cases VPP vswitch is the most
 stressed application, as for each flow vswitch is processing each packet
