4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yelena Krivosheev <yel...@marvell.com>
[ Upstream commit 8466baf788ec3e18836bd9c91ba0b1a07af25878 ]
It is incorrect to enable TX/RX queues (call by mvneta_port_up()) for
port without link. Indeed MTU change for interface without link causes TX
queues to stuck.

network unit")
