Descriptions

usePathMtuDiscovery — RFC Editor

Packet size is either auto-discovered or manually configured. If usePathMtuDiscovery is true, the system utilizes path-mtu to determine the maximum IP-TFS packet size. If the packet size is explicitly configured, then it will only be adjusted downward if use-path-mtu is set.
