252 On the receiving side, if we found a subsection for a device that we

259 If the new data is only needed in a rare case, then the subsection

268 called if the subsection is loaded.
271 loading all subsections, because a newer subsection could change the same
273 post_load can be used to detect whether a subsection was loaded, and to
