There is no this exact error text in your code or DPDK,
I assume we're talking about the quoted fragment.
`flow` is a pointer, the correct error condition is `if (flow == NULL)`,
so your code probably misinterprets success as error.
Also `flow` is not assigned if `rte_flow_validate()` returns non-0.
