So if you get HT_VHT_NOT_INDICATED in the driver, don't you *still*
have to parse the IEs?

Arguably, cfg80211 could know itself by parsing though, so it could
already fall back to that, no?

But if you do that, you already need the parsing code, so then perhaps
it would make sense to just always use the parsing in cfg80211? Or
export a parsing function to use in driver(s)?
