Sorry for my commit message cannot express my view clearly. 
Following is my supplementary explanation of this:

First,  the APIs to be changed are:
1. rte_ring_mp_enqueue
2. rte_ring_sp_enqueue
3. rte_ring_enqueue

Second, Let's use an example to explain this:
1. We call API in form: rte_ring_enqueue(r, obj).
2. Current function header indicates that we will have ring[idx] = *obj.
3. However, this is not the case, what we eventually have is: ring[idx] = obj.

So I think the current function header is misleading or
maybe the implementation of above three functions need to be changed.
