> Add dedicated parameter structure for cuckoo hash. The cuckoo hash from
> librte_hash uses slightly different prototype for the hash function (no
> key_mask parameter, 32-bit seed and return value) that require either
> of the following approaches:
>    1/ Function pointer conversion: gcc 8.1 warning [1], misleading [2]
>    2/ Union within the parameter structure: pollutes a very generic API
>       parameter structure with some implementation dependent detail
>       (i.e. key mask not available for one of the available
>       implementations)
>    3/ Using opaque pointer for hash function: same issue from 2/
>    4/ Different parameter structure: avoid issue from 2/; hopefully,
>       it won't be long before librte_hash implements the key mask feature,
>       so the generic API structure could be used.
