I've just seen that upstream systemd v239 claims to support IPV6MtuBytes https://lwn.net/Articles/758128/
* networkd's .network files now support a new IPv6MTUBytes= option for setting the MTU used by IPv6 explicitly as well as a new MTUBytes= option in the [Route] section to configure the MTU to use for specific routes. It also gained support for configuration of the DHCP "UserClass" option through the new UserClass= setting. It gained three new options in the new [CAN] section for configuring CAN networks. The MULTICAST and ALLMULTI interface flags may now be controlled explicitly with the new Multicast= and AllMulticast= settings. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671951 Title: networkd should allow configuring IPV6 MTU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1671951/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
