This patch adds following features to the routing-pipeline to enable it for various NFV use-cases; 1.Fast-path ARP table enable/disable 2.Double-tagged VLAN (Q-in-Q) packet enacapsulation for the next-hop 3.MPLS encapsulation for the next-hop 4.Add colour (Traffic-class for QoS) to the MPLS tag 5.Classification action to select the input queue of the hierarchical schedular (QoS) The above proposed features can be enabled (or disabled) through the parameters specified in configuration file as below; [PIPELINE0] type = ROUTING core = 1 pktq_in = RXQ0.0 RXQ1.0 RXQ2.0 RXQ3.0 pktq_out = TXQ0.0 TXQ1.0 TXQ2.0 TXQ3.0 n_routes = 4096 n_arp_entries = 1024 ip_hdr_offset = 142 arp_key_offset = 64 l2 = qinq qinq_sched = no The LPM table entries might include additional fields depending upon the packet encapsulation (Q-in-Q, MPLS)for the next-hop. The CLI commands for adding or deleting such entries to LPM table have been implemented. Action handlers for QinQ and MPLS encapsulation, classification action to select the input queue of the hierarchical schedular(QoS) and adding colour (Traffic-class for QoS) to the MPLS tag have been implemented.
