Not sure if we are dealing with a bug here.

How is this supposed to be distributed to the driver? I have been
looking in the mac80211 interface. The only callback that I can think
is is the change_interface() callback although the documentation does
state this is only for changing the interface type. Or is it to be
done upon add_interface()?

You should read the interface address in add_interface and basically
never use perm_addr. change_interface can't change it as it's only
called while an interface is up.
