IIUC, this config item was set for all architectures under make compilation. $ git grep RTE_PMD_PACKET_PREFETCH v20.08 config/ v20.08:config/common_base:CONFIG_RTE_PMD_PACKET_PREFETCH=y Now that we switched to meson, it got lost and this patch only restores it for x86. Can other architectures check this? Thanks. -- David Marchand
