- Enables or disables Path MTU detection for IPv4. If enabled, all packets are sent with DF set, and all
- fragmentation happens on the sending host itself. If disabled, routers may fragment the packets themselves,
- possibly leading to multiple fragmentation. In general, disabling this should not be necessary, but in some
- networks ICMP MTU Too Big packets are lost, so PMTU detection doesn't work correctly.
-
- If possible, fastd's mtu setting should be adjusted so the packets aren't fragmented at all instead of
- relying on this option.

- The default is auto, which uses the system default as specified in /proc/sys/net/ipv4/ip_no_pmtu_disc.

- The pmtu option is available on Linux platforms only.
+ Does nothing; the ``pmtu`` option is only supported for compatiblity
