How reproducible:
100%

1. disconnect from any WiFi, disable WiFi using nm-applet
2. enable WiFi using nm-applet
3. watch ip a / journalctl

Actual results:
Oct 20 20:25:29 sopos-ntb.usersys.redhat.com NetworkManager[30881]: <info>  [1476987929.4813] device (wlp3s0): set-hw-addr: set MAC address to 1E:D0:81:3B:24:B0 (scanning)

This was an intentional change.

This is a duplicate of bug 1387350.

It would be helpful, if you could elaborate (on the other bug) what concrete issue this causes for you. Thanks.
