Hi, I am trying to create some flow rules on VF using DPDK 19.08 rte_flow API. But it returns -38, *Function not implemented* when I called rte_flow_validate(). I bind I40E on PF0 and vfio-pci on VF0 and iavf on VF1 and VF2 I just wanna know can X710's VF create flow rules using rte_flow. Should I set any flags or call any functions to open this ?
