Subject: [PATCH] net: mvneta: fix enable of all initialized RXQs
Date:   Fri, 30 Mar 2018 12:05:31 +0200
Message-Id: <20180330100531.5995-1-gregory.clement@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Yelena Krivosheev <yelena@marvell.com>

In mvneta_port_up() we enable relevant RX and TX port queues by write
queues bit map to an appropriate register.

q_map must be ZERO in the beginning of this process.
