From: Jiayu Hu Date: Fri, 6 Jul 2018 01:02:23 +0000 (+0800) Subject: app/testpmd: enable UDP GSO in csum engine X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=aaacd052cea499e146dbd12f92e7027ec07d505d;p=dpdk.git 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.
