[dpdk-dev] [PATCH v4 09/11] ip_pipeline: added new implementation of firewall pipeline

Maciej Gajdzica maciejx.t.gajdzica at intel.com
Fri Jul 3 10:58:37 CEST 2015


From: Daniel Mrzyglod <danielx.t.mrzyglod at intel.com>

Firewall pipeline implementation is split to two files.
pipeline_firewall.c file handles front-end functions (cli commands
parsing) pipeline_firewall_ops.c contains implementation of functions
done by pipeline (back-end).
