A paper maybe? If I am not mistaken that's just an intent to enable symmetric RSS hash-fun= ction via standard RSS rte_flow API - feature already available with i40e and newest Intel HW. (AFAIK on i40e right now it could be configured via RTE_ETH_HASH_FILTER_SYM= _HASH_ENA_PER_PORT). If so, then I think the author may need to mention what PMDs will support t= hat feature in 19.11.
