ifconfig: mtu: disallow MTU < 1280 bytes when IPv6 is enabled on the interface
Using an MTU less then the required 1280 bytes (as per RFC) on an interface where IPv6 is not explicitly disabled by: - set interfaces ethernet eth1 ipv6 address no-default-link-local - not having any other IPv6 address configured Will now trigger a commit error via verify() instead of raising FileNotFoundError!
