link_local
Description:
Enable and disable the IPv4 link-local configuration independently of the ipv4.
method configuration. This allows a link-local address (169.254.x.y/16) to be obtained in addition to other addresses, such as those manually configured or obtained from a DHCP server.
When set to "auto", the value is dependent on "ipv4.method". When set to "default", it honors the global connection default, before falling back to "auto". Note that if "ipv4.method" is "disabled", then link local addressing is always disabled too. The default is "default".
