[dpdk-dev] [PATCH v3 11/11] ip_pipeline: added new implementation of flow classification pipeline

[Maciej Gajdzica <maciejx.t.gajdzica@intel.com>]

Flow classification pipeline implementation is split to two files.
pipeline_flow_classification.c file handles front-end functions (cli
commands parsing) pipeline_flow_classification_ops.c contains
implementation of functions done by pipeline (back-end).
