[dpdk-dev] [PATCH 2/2] net/mlx5: optimize mprq memcpy for AMD EPYC2 platforms

[Aman Kumar]

Dear Thomas,

Please check V2 patchset
<https://patchwork.dpdk.org/project/dpdk/patch/20211019104724.19416-1-aman.kumar@vvdntech.in/>.
Upon suggestions from Jerin, we've moved this build option using
config/x86/x86_amd_epyc_linux_gcc cross-file.
This option is not a compilation option and enabled by default in V2, once
it is cross built. Please let us know your comments.


*With Best Regards*
