MAC-randomization commonly means that per network (SSID) a MAC address
to be generated and used based on the machine's interface MAC (HW MAC) for
a certain connection and next changed not to be recognized by this network.

However, that doesn't mean that the implementation with overwrite the HW MAC
seen by commands and API. There's no need for that.

This links tells about one such linux distribution, but it seems that
there are no more such cases:

Are you familiar with any other cases?

There are cases when user with enough privileges can overwrite HW MAC,
and so Qt's way seems to be doing a great job by using other
parameters, not MACs.

Kind regards,
