It isn't clear to me, but does your algorithm take into account
interfaces like the one virtualbox sets up for instance?
glaga...@praetorian % ipadm show-if

IFNAME STATE CURRENT PERSISTENT
lo0 ok -m-v------46 ---
vboxnet0 ok bm--------4- ---
yge0 ok bm--------4- ---
vboxnet0 is certainly not an interface that you'd want to use even
though it's configured like any other interface.
