It's not once per driver load, it's once globally.

Once per driver load would be in fact what I would actually
consider more reasonable, so put the boolean state into
struct netdev, and test it to decide whether to do the
WARN_ON() print.

Doing a message every time is way overboard and is going to
spam some people's systems to the point where they can't
even diagnose the problem, so I'm not accepting a patch
which does that.
