If I am not mistaken that's just an intent to enable symmetric RSS
hash-function 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 that
feature in 19.11.
