Overall this looks good, one test checklist item for me was to build
with Gcc 14 and analyzer option. This finds bugs but can generate false
positives. The output is quite verbose.
It complains about this which may or may not be a real problem.
If memcpy() is used instead of rte_memcpy() then the problem goes away.
The issue is that inlined version rte_memcpy() will reference past the arguments
as an internal optimization for small values.
