+=======================
+In vACL, each component is constructed using packet framework pipelines.
 It includes Rx and Tx Driver, Master pipeline, load balancer pipeline and
 vACL worker pipeline components. A Pipeline framework is a collection of input
 ports, table(s),output ports and actions (functions).
 
+---------------------------
 Receive and Transmit Driver
-******************************
+---------------------------
 Packets will be received in bulk and provided to LoadBalancer(LB) thread.
 Transimit takes packets from worker threads in a dedicated ring and sent to
 hardware queue.
 
+---------------------------
 Master Pipeline
-******************************
+---------------------------
 The Master component is part of all the IP Pipeline applications. This component
 does not process any packets and should configure with Core 0, to allow
 other cores for processing of the traffic. This component is responsible for
- 1. Initializing each component of the Pipeline application in different threads
- 2. Providing CLI shell for the user control/debug

 In vFW, each component is constructed using packet framework pipelines.
 It includes Rx and Tx Driver, Master pipeline, load balancer pipeline and
 vfw worker pipeline components. A Pipeline framework is a collection of input
 ports, table(s),output ports and actions (functions).

 The Master component is part of all the IP Pipeline applications. This component
 does not process any packets and should configure with Core 0, to allow
 other cores for processing of the traffic. This component is responsible for
