The following APIs's are implemented in the librte_flow_classify library: rte_flow_classifier_create rte_flow_classifier_free rte_flow_classifier_query rte_flow_classify_table_create rte_flow_classify_table_entry_add rte_flow_classify_table_entry_delete The following librte_table API's are used: f_create to create a table. f_add to add a rule to the table. f_del to delete a rule from the table. f_free to free a table f_lookup to match packets with the rules. The library supports counting of IPv4 five tupple packets only, ie IPv4 UDP, TCP and SCTP packets.
