I was wondering where is the confusion. I interpreted as referring to the esize
parameter in rte_ring_xxx_elem APIs. Anyway, please see below.

I am not bothered much about upper layer functions. I looked at the generate
code for the function __rte_ring_enqueue_elems.
Existing code has the if checks for 8 and 16.
Your patch also has the checks.
My patch does not have the checks as it passes the constants directly without
using esize[] array in functions test_ring_burst_bulk_tests4.
