commit 3762b3e2aa6c885ecfbdaf6fb9b3f6f0eef950b5 Author: Greg Kroah-Hartman Date: Wed May 30 22:25:17 2018 +0200 Linux 4.9.105 commit 98d69fb3b175855cdd4c37d41a4b477a0860b1a0 Author: Greg Kroah-Hartman Date: Wed May 30 20:44:08 2018 +0200 Revert "vti4: Don't override MTU passed on link creation via IFLA_MTU" This reverts commit d82309e24315a99a29342d330f6142122e249963 which is 03080e5ec727 ("vti4: Don't override MTU passed on link creation via IFLA_MTU") upstream as it causes test failures. This commit should not have been backported to anything older than 4.16, despite what the changelog said as the mtu must be set in older kernels, unlike is needed in 4.16 and newer. Thanks to Alistair Strachan for the debugging help figuring this out, and for 'git bisect' for making my life a whole lot easier.
