Hi Ben,

  *   Yes, definitely.  C11/C17 stdatomic.h is high on the list.
  *   Our current critical path item for MSVC DPDK support is TLS.

Hi Thomas,

  *   I will setup some time next week to discuss alignment and share our proposed MSVC plan.

Please no.  We are actively working with the MSVC team to extend support for DPDKs dependencies

Could you get them to implement C11 atomics? The MSVC support for atomic
operations is poor, unless it's changed since I last looked. We could remove
quite a bit of rather awful stuff if either MSVC supported the C standard or if
OVS dropped support for MSVC.
