From bb58239767adc45c81b78a9505224c518aeee8b8 Mon Sep 17 00:00:00 2001 From: Jijiang Liu Date: Fri, 13 Feb 2015 10:22:46 +0100 Subject: [PATCH] ethdev: add outer IP checksum capability flag If the flag is advertised by a PMD, the NIC supports the outer IP checksum TX offload of tunneling packets, therefore an application can set the PKT_TX_OUTER_IP_CKSUM flag in mbufs when transmitting on this port.
