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.

  net/i40e: add support for MARK + RSS action in rte_flow
  net/i40e: add runtime option to disable vector rx
  net/i40e: fix inadvertent override of vector RX allowance
