I understand the need, but you dont consider the unbind/unload part.

Moreover since I needed a similar mechanism for testing (multiple
protocols in a single driver), I posted yesterday a patch that does this
same thing that since I was using since ages but never posted (and it
takes care of unload/unbind too.).

Please drop this patch and use the above (that soon should be in -next)

Thanks,
Cristian
