Subject: [PATCH net-next v2 6/7] net: mvneta: Verify hardware checksum only when offload checksum feature is set
Date: Fri, 13 Jul 2018 18:18:40 +0200	[thread overview]
Message-ID: <20180713161841.11202-7-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20180713161841.11202-1-gregory.clement@bootlin.com>

From: Yelena Krivosheev <yelena@marvell.com>

If the checksum offload feature is not set, then there is no point to
check the status of the hardware.
