It's certainly true that the driver-local index isn't usable for the
association (not even if one remembers, say, the slot association,
since a card can presumably be moved).

Out of curiosity, though, isn't there a residual related problem, in
that a reinserted card gets a new eth# as well? Not insurmountable, I
suppose, but a bitch to automate.
