3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steffen Klassert <steffen.klassert@secunet.com>
[ Upstream commit 78ff4be45a4c51d8fb21ad92e4fabb467c6c3eeb ]
We need to initialize the fallback device to have a correct mtu set on this device. Otherwise the mtu is set to null and the device is unusable.
