Subject: ip_tunnel: Initialize the fallback device properly
From: Steffen Klassert <steffen.klassert@xxxxxxxxxxx>
[ 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.
Fixes: fd58156e456d ("IPIP: Use ip-tunneling code.")
