Hi,

I remember there's no legacy API rte_eth_dev_filter_ctrl()  supported in 20.11.
Please refer to RSS Flow part in i40e.rst:

Enable hash and set input set for ipv4-tcp.
    testpmd> flow create 0 ingress pattern eth / ipv4 / tcp / end \
      actions rss types ipv4-tcp l3-src-only end queues end / end

BR,
Beilei
