Change Details

In some cases, like a WAN Loadbalance configuration with different MTU in the WAN interfaces, PMTU still needed to make sure sites that are MTU-dependent doesn't break when the WAN switching to the interface that has a different MTU (happens when it has lower MTU) than the initial WAN interface. As tcp-mss pmtu is currently removed in followup of [[ https://phabricator.vyos.net/T2868 | T2868 ]] and this feature request made in followup for [[ https://phabricator.vyos.net/T2868#80746 | T2868#80746 ]] to move tcp-mss pmtu to different CLI with different logic.
