5e69724a8a
Added support for the following properties in connection profile:
id (VNI), remote IPv4/IPv6, ttl, tos, df, destination port.
See IP-LINK(8) manual page with command `man 8 ip-link` for more details
on the properties. See also previous commit for nm supported attributes.
id and remote are mandatory attributes:
```
$ nmcli connection add type geneve save no
Error: 'id' argument is required.
$ nmcli connection add type geneve id 42 save no
Error: 'remote' argument is required.
```
