[dpdk-dev] [PATCH v1 5/6] examples/flow_classify: flow classify sample application
Bernard Iremonger
bernard.iremonger at intel.com
Wed Aug 23 15:51:14 CEST 2017
The flow_classify sample application exercises the following
librte_flow_classify API's:
rte_flow_classify_create
rte_flow_classify_validate
rte_flow_classify_destroy
rte_flow_classify_query
It sets up the IPv4 ACL field definitions.
It creates table_acl using the librte_table API.
