>=20
> When create softnic hash table with 16 keys, it failed on 32-bit
> environment, because the pointer field in structure rte_bucket_4_16
> is only 32 bits. Add a padding field in 32-bit environment to keep
> the structure to a multiple of 64 bytes. Apply this to 8-byte and
> 32-byte key hash function as well.
