Subject: [dpdk-dev] [PATCH 13/14] net/sfc: support inner checksum offload on transmit
Date: Sun, 24 Dec 2017 10:46:43 +0000 [thread overview]
Message-ID: <1514112404-13398-14-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1514112404-13398-1-git-send-email-arybchenko@solarflare.com>
There is no dedicated controls for inner checksum offload on
device/queue level. So, enable together with outer offloads.
