Subject: [PATCH] net: mvneta: fix enable of all initialized RXQs
Date: Fri, 30 Mar 2018 12:05:31 +0200 [thread overview]
Message-ID: <20180330100531.5995-1-gregory.clement@bootlin.com> (raw)
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.
