Do not use a random MAC address for the GAS exchange that is used as part of the DPP protocol exchange since that would break DPP. Configurator expects the same MAC address to be used for DPP Authentication exchange and DPP Configuration exchange (GAS). Since the DPP Authentication exchange has already used the MAC address configured on the interface, use of a random address for the GAS exchange would not provide any additional privacy protection. If a random MAC address needs to be used for this type of an exchange, that random address would need to be first configured on the interface before starting DPP exchange. This does not change GAS query behavior for any other use case, i.e., the gas_rand_mac_addr configuration continues to apply to all the Interworking/Hotspot 2.0 uses.
