This is needed for auxiliary drivers that implement MACsec offload, but have flows which are triggered over the macsec net_device, this allows the drivers in such cases to verify if the device is offloaded or not, and to access the real device of that macsec device, which would belong to the driver, and would be needed for the offload procedure.
