+Subject: Revert "vti4: Don't override MTU passed on link creation via IFLA_MTU"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 33cebc976c3b77bdf8f3fb4478cf776131ebfe4f 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.
