net: switchdev: pass callback to dump operation
Similar to the notifier_call callback of a notifier_block, change the function signature of switchdev dump operation to: int switchdev_port_obj_dump(struct net_device *dev, enum switchdev_obj_id id, void *obj, int (*cb)(void *obj)); This allows the caller to pass and expect back a specific switchdev_obj_* structure instead of the generic switchdev_obj one. Drivers implementation of dump operation can now expect this specific structure and call the callback with it. Drivers have been changed accordingly.
