Subject[PATCH 4.9 227/329] net: mvneta: fix enable of all initialized RXQs
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yelena Krivosheev <yelena@marvell.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.
