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 su=
ch
virtual channel between PF and VF in share code. Due to the principle align=
ed
with i40e kernel driver develop, we cannot add new virtual channel by ourse=
lves.
So I did it this way on DPDK when DPDK using as PF driver.

Thanks
