This patch series adds two inbuilt nodes ip4_lookup_fib and ip6_lookup_fib in graph library. These nodes uses the existing Forwarding Information Base (FIB) library to create FIB, to do route addition and route lookup.
Two new commands (for ipv4 and ipv6) for providing the lookup mode is added in the dpdk-graph application. fib or lpm can be given as lookup mode. If these new lookup mode commands are not given, the dpdk-graph uses lpm (Longest Prefix Match) or lpm6 by default. If fib is given as lookup mode then the ip4_lookup_fib or ip6_lookup_fib nodes are used by the application. v2: - Fixed build failure in DPDK CI. - Changed the prefetch code in process functions. Also removed the prefetch of mbuf obj as it was not improving performance. - Added code to control fib configuration from dpdk-graph application. - Added the packet classification next nodes id in public header file, so that they can be used by library and application. - Changed the macro FIB_DEFAULT_NH to point to pkt drop node.
