I have sent V6. This has the test cases added for 'rte_ring_xxx_elem' APIs. All issues are fixed in both the methods of copy, more info below. I will post the performance info soon.

Same here, 'idx' needs to be normalized to elements of type 'uint32_t' and similar fixes on other variables. I have applied your suggestion in 6/6 in v6 along with my corrections. The rte_ring_elem test cases are added in 3/6. I have verified that they are running fine (they are done for 64b alone, will add more). Hopefully, there are no more errors.
