Replace macro __rte_packed with __rte_packed_begin to push existing pack value and set packing to 1-byte and macro __rte_packed_end to restore the pack value prior to the push. Macro __rte_packed_end is deliberately utilized to trigger a MSVC compiler warning if no existing packing has been pushed allowing easy identification of locations where the __rte_packed_begin is missing.
