cfg80211: export multiple MAC addresses in sysfs
If a device has multiple MAC addresses, userspace will
need to know about that. Similarly, if it allows the
MAC addresses to vary by a bitmask.
If a driver exports multiple addresses, it is assumed
that it will be able to deal with that many different
addresses, which need not necessarily match the ones
programmed into the device; if a mask is set then the
device should deal addresses within that mask based
on an arbitrary "base address".
To test it all and show how it is used, add support
to hwsim even though it can't actually deal with
addresses different from the default.
