    Description

      Running the following program :

      #include <QNetworkInterface>
      #include <QDebug>
      
      int main()
      {
        for(auto &&iface : QNetworkInterface::allInterfaces()) {
          qDebug() << iface << iface.type();
        }
      }
      

      produces correct output, but leads to the following kernel warning on Linux 6.3.6 :

      warning: `foobar' uses wireless extensions which will stop working for Wi-Fi 7 hardware; use nl80211
      

      The culprit is most probably the SIOCGIWMODE ioctl issued here : Qt6 , Qt5.
