[PATCH v2 0/4] app: introduce testgraph application

[Vamsi Attunuru]

This patch series introduces testgraph application that verifies graph
architecture, it provides an infra to verify the graph & node libraries
and scale the test coverage by adding newer configurations to exercise
various graph topologies & graph-walk models required by the DPDK
applications.

Also this series adds two new nodes (punt_kernel & kernel_recv) to the
node library.

V2:
* Handle error checks in testgraph application
* Extend supported test node patterns
* Fix warnings

Vamsi Attunuru (4):
  node: add pkt punt to kernel node
  node: add a node to receive pkts from kernel
  node: remove hardcoded node next details
  app: add testgraph application
