[STDS-802-Privacy] Random MAC addresses on Linux
The current snapshot of the wpa_supplicant development branch includes
experimental support for randomizing the local MAC address for both
pre-association (active scan and GAS/ANQP while not connected) and
connected cases. This behavior can be configured separately for each.
The configuration parameters are described in the main commit:

Please note that this requires a driver that supports MAC address
changes (e.g., ath9k). While number of Linux drivers do have that
functionality, some don't support it at all or just claim to have
changed the address while not really having changed anything for the
actual over-the-air frames.. Anyway, I hope this can provide
relatively convenient tool for experimentation.
