[v6,00/12] add CLI based graph application

  From: Sunil Kumar Kori <skori@marvell.com>

In the continuation of following feedback
https://patches.dpdk.org/project/dpdk/patch/20230425131516.3308612-5-vattunuru@marvell.com/
this patch series adds dpdk-graph application to exercise various
usecases using graph.

1. Each use case is defined in terms of .cli file which will contain
set of commands to configure the system and to create a graph for
that use case.

2. Each module like ethdev, mempool, route etc exposes its set of commands
to do global and node specific configuration.

3. Command parsing is backed by command line library.

Rakesh Kudurumalla (5):
  app/graph: add mempool command line interfaces
  app/graph: add ipv6_lookup command line interfaces
  app/graph: add ethdev_rx command line interfaces
  app/graph: add graph command line interfaces
  app/graph: add l3fwd use case

Sunil Kumar Kori (7):
  app/graph: add application framework to read CLI
  app/graph: add telnet connectivity framework
  app/graph: add parser utility APIs
  app/graph: add ethdev command line interfaces
  app/graph: add ipv4_lookup command line interfaces
  app/graph: add neigh command line interfaces
  app/graph: add CLI option to enable graph stats
