  this change is not cherry-picked from master, because master has
  picked up an updated SPDK which is in turn using a DPDK containing fixes like
  a385972c, 3370975b,  74f27710 and e5e193ac and a36b40dd. these changes either
  disables the"address-of-packed-member" warnings or addresses
  "error=stringop-truncation" warnings.
