Here is the latest iteration of the proposed change to allow struct rte_mbuf to be consumed by MSVC.
* Introduce an internal __rte_marker macro conditionally expanded for MSVC vs existing users of the struct. At some point we can uncomment __rte_deprecated to assist migration away from the current marker fields for applications after appropriate announcement periods etc.. * Introduce anonymous unions to allow aliasing of the previous named offsets by a *new* name. The intention would be to convert the dpdk tree to use the new names along with this change and enable __rte_deprecated for dpdk builds (not applications) to avoid accidental re-introduction. * The anonymous unions are now also used to pad cacheline0 and cacheline1 instead of __rte_cache_min_aligned. * Converted the type of the fields for the named markers to char[] instead of uint8_t[].
