I have recently installed Kali 2020.2 and have just noticed that any "dormant" network interfaces appear to have random MAC addresses assigned periodically!?

I was wondering where this is configured, and thus how it is possible to disable it?

The following demonstrates the modified MAC address, with permaddr showing the original hardware/MAC address:

# ip link show wlan0
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 2312 qdisc mq state DORMANT mode DORMANT group default qlen 1000
    link/ether 02:02:02:02:02:02 brd ff:ff:ff:ff:ff:ff permaddr 01:01:01:01:01:01
I had a scout around, and thought that I had found the answer in /etc/network/if-pre-up.d/macchanger. However, the log (/var/log/macchanger.log) showed that this script was disabled in /etc/default/macchanger.

Hence, it seems that this feature/functionality has been duplicated elsewhere, but I am unable to locate where it has been duplicated. Any help will be gratefully received; thank you in advance.
