Hi zhulei, The commit 7c31e54aeee5 ("vxlan: do not destroy fdb if register_netdevice() is failed") was not backported to 4.19-stable tree. https://lore.kernel.org/stable/15641355392228@xxxxxxxxx/ So, you can request a backport. Please check the URL: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html Thanks a lot! Taehee Yoo
