 - Number of NFs per service instance (e.g. 1,2,4..10).
 
-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.

 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
