Sorry I don't follow you with "ABI is the same".
Can you explain please?


I am not against the fix, but it seems to test something different
than what an application using the hash library would do.
Or if an application directly calls this hash function, maybe the unit
test should not test it via rte_hash_create (which seems to defeat the
abstraction).
