Subject: [dpdk-dev] [PATCH] examples/ipsec-secgw: Update checksum while decrementing ttl
Date: Mon, 26 Sep 2016 22:02:58 +0530 [thread overview]
Message-ID: <20160926163300.22990-1-akhil.goyal@nxp.com> (raw)
From: Akhil Goyal <akhil.goyal@nxp.com>
In IPsec-secgw application when TTL is decremented in IP header
before forwarding the packet, checksum needs to be updated.
In this patch an incremental checksum is added.
Other applications(like l3fwd) are also doing so.
