[PATCH v3 0/3] node: Introduce kernel_rx & kernel_tx nodes

[Vamsi Attunuru]

This patch set introduces two new nodes to transmit & receive packets
from kernel. This nodes can be used for any exception path handling or
to forward any control plane traffic to kernel or receive from kernel stack.

V3:
* Address review comments
* Drop test-graph application from the patch set

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

Vamsi Attunuru (3):
  node/kernel_tx: support packet transmit to kernel
  node/kernel_rx: support receiving packets from kernel
  node/ethdev_rx: remove hardcoded node next details
