Subject: [PATCH net-next v2 3/7] net: mvneta: increase number of buffers in RX and TX queue
Date: Fri, 13 Jul 2018 18:18:37 +0200	[thread overview]
Message-ID: <20180713161841.11202-4-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20180713161841.11202-1-gregory.clement@bootlin.com>

From: Yelena Krivosheev <yelena@marvell.com>

The initial values were too small leading to poor performance when using
the software buffer management.
