@gloinul assuming the value can be updated dynamically, and isn't just a transport parameter, couldn't you send the update **in** your PMTUD probe packet? If the packet makes it and gets acknowledged, then everything is good. If the packet was too big, the packet doesn't make it, doesn't get acknowledged and then the peer doesn't even know you tried to increase it.
