Subject: [PATCH 1/2] net: nixge: Do not zero application specific fields in desc
Date: Fri, 10 Aug 2018 18:19:40 -0700 [thread overview]
Message-ID: <20180811011941.6187-2-mdf@kernel.org> (raw)
In-Reply-To: <20180811011941.6187-1-mdf@kernel.org>
Do not zero application specific fields in DMA descriptors.
The hardware does ignore them, so should software.
