From aaacd052cea499e146dbd12f92e7027ec07d505d Mon Sep 17 00:00:00 2001 From: Jiayu Hu Date: Fri, 6 Jul 2018 09:02:23 +0800 Subject: [PATCH] app/testpmd: enable UDP GSO in csum engine This patch enables GSO for UDP/IPv4 packets. Oversized UDP/IPv4 packets transmitted over a GSO-enabled port will undergo segmentation.
