What an interesting corner case.  I assume that there's a good
(speed?) reason why init_etherdev doesn't use dev_alloc_name() or
equiv.

Of course, I never thought anyone would rename interfaces to the names
of other interfaces, so I never honestly considered it.  It was more
for large ISPs to name interfaces after their clients (I had a pppd
hack that did this), for filtering and easy identification purposes.
