[dpdk-dev] Experimental symbols in flow_classify lib

[Kinsella, Ray]

Hi Bernard, 

The following flow_classify experimental symbols are present in both v21.05 and v19.11 release. These symbols should be considered for promotion to stable as part of the v22 ABI in DPDK 21.11, as they have been experimental for >= 2yrs at this point. 

 * 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
 * rte_flow_classify_validate
