Subject: [PATCH 3.18 108/185] net: mvneta: fix enable of all initialized RXQs
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yelena Krivosheev <yelena@...vell.com>
[ Upstream commit e81b5e01c14add8395dfba7130f8829206bb507d ]
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.
