    testpmd> flow create 0 ingress pattern eth / ipv4 src is 192.168.0.3 dst is 192.168.0.4 / udp src is 22 dst is 65536 / end actions queue index 0 / end

testpmd> flow create 0 ingress pattern eth / ipv4 src is 192.168.0.3 dst is 192.168.0.4 / udp src is 65536 dst is 33 / end actions queue index 0 / end
Bad arguments
the rule failed to be created.
I tried TCP/SCTP rule, and got the same result.
  I tried validating the rule instead of creating the rules with wrong sport/dport, and got the same result.
The bug is fixed.
