Applications using DPDK, including but not limited to OVS DPDK, utilize rte_flow to benefit from hardware flow offloads. Three patches in this set improves i40e offload capabilities by
(*) Enhancing Flow Director to support MARK + RSS action combination (*) Giving applications ability to disable vector RX at runtime, since Flow Director is not currently supported using the vector RX path For example, with this patchset, OVS DPDK's existing hw-offload feature becomes functional using i40e, improving phy-to-phy switching performance more than 200% for a use case with 1,000,000 UDP flows switched by 1,000 rules in Open Flow tables.
