So the first steps are to figure out what settings are actually needed
for 6to4.  That basically means figuring out the configuration and
values that existing tools require.  Fedora has some scripts that do
this that might be a guide, and I'm sure other distros automate this
too.

After you've come up with a list, we get to create a new NMSetting
subclass that holds these values and can validate the settings that a
user provides.

Then we write the code in NM to set up the 6to4 tunnel based on those
settings.
