I'm not seeing anything obvious in the network stack with a quick skim,
but before we start relying on the property that interface indicies are
not globally unique I expect an good hard look at the networking stack
to see if any of those cases where there were problems still exist.

Just an idea -- is it worth moving the possibility to have ifindidces intersect
under CONFIG_<SOMETHING> (EXPERT/CHECKPOINT_RESTORE) to let wider audience check
the code in real-life?
