Yes, if VM can configure through rte_eth_dev_filter_ctrl, it will be better.
But flow director can only be programed on PF, and currently there is no such
virtual channel between PF and VF in share code. Due to the principle aligned
with i40e kernel driver develop, we cannot add new virtual channel by ourselves.
So I did it this way on DPDK when DPDK using as PF driver.

Thanks
