> Relax ordering(RO) is one feature of 82599 NIC, to enable this feature can
> enhance the performance for some cpu architecure, such as SPARC and so on.
> Currently it only supports one special cpu architecture(SPARC) in 82599
> driver to enable RO feature, this is not very common for other cpu architecture

> This patch add one common config CONFIG_ARCH_WANT_RELAX_ORDER to set RO feature,
