Hi,

I have two questions regarding mempools:

- the first is trivial: how do you delete them? Can you? I can't see a 
function to do that, and none of the examples are doing such thing. When 
exactly it get deleted?
- during creation, cache_size have one requirement: it has to be smaller 
than RTE_MEMPOOL_CACHE_MAX_SIZE. And one recommendation: "n modulo 
cache_size == 0". Is there any more guideline to determine that number? 
E.g. now I'm using the biggest number which fits the above two conditions.

Regards,

Zoltan
