* nmp_cache_update_netlink:
* @cache: the platform cache
* @obj_hand_over: a #NMPObject instance as received from netlink and created via
* nmp_object_from_nl(). Especially for link, it must not have the udev
* replated fields set.
* This instance will be modified and might be put into the cache. When
* calling nmp_cache_update_netlink() you hand @obj over to the cache.
* Except, that the cache will increment the ref count as appropriate. You
* must still unref the obj to release your part of the ownership.
* @is_dump: whether this update comes during a dump of object of the same kind.
* kernel dumps objects in a certain order, which matters especially for routes.
* Before a dump we mark all objects as dirty, and remove all untouched objects
* afterwards. Hence, during a dump, every update should move the object to the
* end of the list, to obtain the correct order. That means, to use NM_DEDUP_MULTI_IDX_MODE_APPEND_FORCE,
* instead of NM_DEDUP_MULTI_IDX_MODE_APPEND.
* @out_obj_old: (allow-none): (out): return the object with same ID as @obj_hand_over,
* that was in the cache before update. If an object is returned, the caller must
* unref it afterwards.
* @out_obj_new: (allow-none): (out): return the object from the cache after update.
* The caller must unref this object.
*
* Returns: how the cache changed.
*
* Even if there was no change in the cace (NMP_CACHE_OPS_UNCHANGED), @out_obj_old
