No, its just a really bad driver :)

See how the driver doesn't support any interface combinations?  It just means 
this device is stuck in station mode with a single interface.  So the driver 
doesn't even bother setting a permanent address on the phy.  It only sets it on 
the default netdev that was created.  Since mac randomization is disabled by 
default, we keep using that one.

We probably should limit AddressRandomizationRange setting for such drivers to 
'full'.

No offloading either for this driver, so you're stuck with WPA2 only.
