But Avahi provides more functionality (e.g. mdns) than merely
configuring network interfaces, so disabling it altogether may
be undesired.
So hopefully there's a way to keep Avahi and still avoid that interface
being configured in such a dummy way.
[ I thought Avahi only did such configuration as a "last recourse", so
there's a chance that you're only seeing the effect of another problem
which prevents the interface from being configured properly and
there's just no need to worry about preventing this dummy config:
just find and fix the other problem, and then Avahi won't kick in. ]
