Subject: [dpdk-dev] [PATCH 2/3] app/testpmd: enable UDP GSO in the checksum forwarding engine
Date: Tue, 29 May 2018 15:41:09 +0800	[thread overview]
Message-ID: <1527579670-91026-3-git-send-email-jiayu.hu@intel.com> (raw)
In-Reply-To: <1527579670-91026-1-git-send-email-jiayu.hu@intel.com>

This patch enables GSO for UDP/IPv4 packets. Oversized UDP/IPv4
packets transmitted over a GSO-enabled port will undergo segmentation.
