Subject: [PATCH v3 net-next 1/6] net: mvneta: Optimize rx path for small frame
Date: Tue, 29 Nov 2016 10:37:21 +0100 [thread overview]
Message-ID: <50c3bed2264b0755205c622e72fc5e00cbe28233.1480412215.git-series.gregory.clement@free-electrons.com> (raw)
In-Reply-To: <cover.a09aeaf5ba62853d595153626b6121ef52a3e9b4.1480412215.git-series.gregory.clement@free-electrons.com>
In-Reply-To: <cover.a09aeaf5ba62853d595153626b6121ef52a3e9b4.1480412215.git-series.gregory.clement@free-electrons.com>
For small frame reuse the phys_addr variable instead of accessing the
uncacheable value in the rx descriptor.
