Subject: [dpdk-dev] [PATCH 20/36] net/sfc: support IPv4 header checksum offload for EF100 Tx
Date: Tue, 13 Oct 2020 14:45:37 +0100	[thread overview]
Message-ID: <1602596753-32282-21-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1602596753-32282-1-git-send-email-arybchenko@solarflare.com>

Use outer layer 3 full checksum offload which does not require any
assistance from driver.
