HT type can`t be advisory, as there may be stations without n.
Our card is set to HT40+/- if set by iw.
Some other station is added into our internal station list by its HT beacons.
E.g. if we have configured HT40- and there is someone with HT40+, minstrel_ht
should use HT20 only. But i admit it seems cleaner to AND both caps.

Yeah, but it's possible to still communicate with them.

Well. You need to consider more than just this. I have a feeling you're
only considering fixed channel use cases. But if we configure HT40+, and
then find a peer on a channel that may only use HT40-, then what?
