network: Allow configuring random MAC addresses
Last modified: 2017-12-14 19:43:58 UTC
Recent versions of NetworkManager introduced support for MAC address spoofing. I think it is quite likely that a user would want this set differently than the default provided by upstream or their distro. Maybe the user needs address randomization turned off to work with a particular network, or maybe the user wants to make sure that randomization is always on when scanning for Wi-Fi networks. https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/
