Hi,

You need to pass --pkt-filter-mode=perfect or --pkt-filter-mode=signature on the commandline to enable flow director. If it isn't enabled you will see something like the following and you will get the "Operation not supported" message in several places:

  testpmd> show port fdir all

  ######################## FDIR infos for port 0      ########################
  MODE:   DISABLE
  SUPPORTED FLOW TYPE:  ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv6-tcp ipv6-udp ipv6-sctp ipv6-other
  FLEX PAYLOAD INFO:

John.
