[PATCH net-next 02/11] net: Introduce new api for walking upper and lower devices

This patch introduces netdev_walk_all_upper_dev_rcu, netdev_walk_all_lower_dev and netdev_walk_all_lower_dev_rcu. These functions recursively walk the adj_list of devices to determine all upper and lower devices. The functions take a callback function that is invoked for each device in the list.
