I still think returning a value from a data input is a kind of hash.
And this is my wikipedia argument:
	https://en.wikipedia.org/wiki/List_of_hash_functions
"This is a list of hash functions, including cyclic redundancy checks,
checksum functions, and cryptographic hash functions."

Anyway, I must accept the community decision.
Now I would like to see a clear explanations of which algos are in
librte_hash, and why we have CRC32c and Toeplitz.
