The problem is that this setup is ambigous. The kernel doesn't
know what device you are using for primary and for secondary IPs.
Device lo is valid device for primary IPs. It is not allowed to
define one IP both as primary and secondary one.

Yes, lo is first in the device list and we search for hidden
IP in _any_ device. We don't have a preferred device to start from.

Yes, this is limitation that nobody wants to fix. Someone
have to persuade me with a clear fix for this.
