MTU settings cannot be applied when IPv6 is disabled
Closed, ResolvedPublicBUG

Description

It seems that the code that controls MTU on an interface was suddenly placed in the wrong place which made it depend on IPv6 global settings.
https://github.com/vyos/vyos-1x/blob/bafb1973d906707cb571385e994a949d0d90b645/python/vyos/ifconfig/interface.py#L1501-L1531

Most likely, MTU-related code should be outside of if sysctl_read('net.ipv6.conf.all.disable_ipv6') == '0'.
