Subject: [dpdk-stable] [PATCH] config: enable packet prefetching with Meson
Date: Fri, 13 Nov 2020 15:52:12 +0100
Message-ID: <> (raw)

With Make build system, RTE_PMD_PACKET_PREFETCH was enabled
by default. It got lost when transitioning to Meson build

In order to avoid performance changes, this patch enables
packet prefetching in rte_config.h.

Hi Bruce,

We were not sure whether adding below Fixes tag so that it is
backported to LTSes. What do you think?

Fixes: 9314afb68a53 ("drivers: add infrastructure for meson build")
