| Subject: ip_tunnel: Initialize the fallback device properly |
| |
| 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. |
| |
| Fixes: fd58156e456d ("IPIP: Use ip-tunneling code.") |
