- * This function is used to do configuration i40e existing RSS with rte_flow.

- * Action is used to transmit parameter like queue index and HASH
- * function for RSS, or flowtype for queue region configuration.
- * For example:
- * pattern:
- * Case 1: try to transform patterns to pctype. valid pctype will be
- * used in parse action.
- * Case 2: only ETH, indicate flowtype for queue region will be parsed.
- * Case 3: only VLAN, indicate user_priority for queue region will be parsed.
- * So, pattern choice is depened on the purpose of configuration of

- * action:
- * action RSS will be used to transmit valid parameter with
