Subject: [dpdk-dev] [PATCH v2 2/3] i40e:support outer IPv4 checksum capability
Date: Tue, 9 Dec 2014 21:17:47 +0800 [thread overview]
Message-ID: <1418131068-7657-3-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1418131068-7657-1-git-send-email-jijiang.liu@intel.com>
The DEV_TX_OFFLOAD_OUTER_IPV4_CKSUM flag is added in i40e capability set, which means the i40e supports TX checksum offload of tunneling packet.
