Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from the private struct by converting it into a pointer. Then use the leverage the new alloc_netdev_dummy() helper to allocate and initialize dummy devices.
