Thanks for taking the time to work on this Brian.

I wonder if we aren't just trading one evil for another.

Right now just configuring bonding will get the bonding
module loaded and the ipv6 facilities will be visible.

Now with your change, the user has to explicitly load
the module.  That's extremely user-unfriendly.
