Well, I'm writing a packet defragmenting code. I have a data structure 
consisting of a rte_hash, a rte_ring and an array allocated with 
rte_zmalloc. All these besides the ring can be freed. So looks like I 
can't destruct my object after allocating. Strictly speaking, I don't 
have to. The need shouldn't arise in normal situation. I just considered 
writing allocating/deallocating function pairs and processing all 
allocation errors to be a good practice.

Isn't it a bit strange to have rte_hash_free() and not have 
rte_ring_free()? What's the reason for this?

Best wishes,
Dmitry
