--- Comment #13 from Steve Yang (stevex.yang at intel.com) ---
Not a bug.

Correct use steps：
1. bind the pf to dpdk driver::
    ./usertools/dpdk-devbind.py -b igb_uio 1b:00.0

2. add one vf on dpdk pf, then bind the vf to vfio-pci::
  echo 1 >/sys/bus/pci/devices/0000:1b:00.0/max_vfs
   ./usertools/dpdk-devbind.py -b igb_uio 1b:02.0

3. launch the app ``testpmd`` with the following arguments::
   ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -w 1b:00.0
--file-prefix=pf – -i --rxq=4 --txq=4

    testpmd> set verbose 1
    testpmd> start


    ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -w 1b:02.0
--file-prefix=vf – -i --rxq=4 --txq=4

     testpmd> set verbose 1
     testpmd> start

4. create filter rule and sent pkg::
flow create 0 ingress transfer  pattern eth / ipv4 src is 11.11.11.11 dst is
12.12.12.12 proto is 255 / vf id is 0 / end actions queue index 1 / end

sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=255)/("X"*480)],
iface="enp27s0f1", count=1)

5. flow create 0 ingress transfer  pattern eth / ipv4 src is 11.11.11.11 dst is
12.12.12.12 / udp / vf id is 0 / end actions queue index 1 / end

sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=17)/("X"*480)],iface="enp27s0f1",
count=1)


Note:
① dst mac is a random mac address, not a pf mac
② proto is 17 means UDP, so create the following rule  and send the packet with
proto is 17 cannot matched。

flow create 0 ingress transfer  pattern eth / ipv4 src is 11.11.11.11 dst is
12.12.12.12 proto is 17 / vf id is 0 / end actions queue index 1 / end

sendp([Ether(dst='3C:FD:FE:DC:F1:88')/IP(src='11.11.11.11',dst='12.12.12.12',proto=17)/("X"*480)],
iface="enp27s0f1", count=1)
