Re: [dpdk-stable] [dpdk-dev] [PATCH v3] net/i40e: Fail rte_flow MARK requests if RX func was vectorized

[Ye Xiaolong <xiaolong.ye@intel.com>]

Latest update, since i40e now has added FDIR ID to vector rx after patchset
https://patches.dpdk.org/cover/60820/ being merged, this patch is no longer
needed, so just drop it from next-net-intel.

Thanks,
Xiaolong
