I've been finding that rte_hash is designed only for some very specialized 
purposes. It doesn't work well if you use unexpected sizes of keys or want 
behavior that isn't precisely doing what the designers of the hash used it 
for... it's not very general-purpose.

I did try to point out one example of the issue but I didn't get much response 
yet to my questions about its limitations and whether a more general-purpose 
table was available, or at least some discussion what rte_hash is for and what 
it's not for.

Matthew.
