I suspected the types mask was not allowed to overlap for the
iftype_data entries, but may be worth documenting that in struct
ieee80211_sband_iftype_data kerneldoc.
Sure, I'll add it.
Actually, looking into this again, I'm not sure I understand your
comment. AFAICT this prevents the same type from appearing twice,
right? I don't get the "not allowed to overlap"... Can you clarify?
I mean that iftdata entries can not overlap by having the same iftypes
set in their mask. So yes, a particular iftype may only be used in a
single entry (yet another way to say it ;-) ).
