Maybe the network drivers are few enough that it will get fixed, or
maybe the WARN_ON_ONCE() will just be removed and the rule not
reinforced.

I personally suspect the latter, since it seems to happen with just
about _any_ random network driver, including the common and
well-maintained ones (ie the Gods only help us for the truly
odd/random cases)

Yes, we'll see how this plays out.

Ian Schram just posted a patch for the NULL pointer derfer in
wireless Ingo reported, so we'll see if that bug will be fixed
now as well.
