The per-wiphy information is getting large, to the point where with more than the typical number of channels it's too large and overflows, and userspace can't get any of the information at all. To address this (in a way that doesn't require making all messages bigger) allow userspace to specify that it can deal with wiphy information split across multiple parts of the dump, and if it can split up the data. This also splits up each channel separately so an arbitrary number of channels can be supported. Additionally, since GET_WIPHY has the same problem, add support for filtering the wiphy dump and get information for a single wiphy only, this allows userspace apps to use dump in this case to retrieve all data from a single device. As userspace needs to know if all this this is supported, add a global nl80211 feature set and include a bit for this behaviour in it.
