From 048a2aa3f30c90c7f9339a17bfd1e663e379625f Mon Sep 17 00:00:00 2001 From: Maxime Coquelin Date: Fri, 13 Nov 2020 15:52:12 +0100 Subject: [PATCH] config: enable packet prefetching with Meson With Make build system, RTE_PMD_PACKET_PREFETCH was enabled by default. It got lost when transitioning to Meson build system. In order to avoid performance changes, this patch enables packet prefetching in rte_config.h.
