      forcedeth: Use napi_complete() not __napi_complete(). · 6c2da9c2
      David S. Miller authored
      
      
      It's not enough that forcedeth's interrupts are disabled,
      local cpu interrupts have to unconditionally be off
      when we remove the device from the poll list.
      
      Based upon a crash report from
      Alexander Beregalov <a.beregalov@gmail.com>:
