This implements ht-cap over-rides for mac80211 drivers.
HT may be disabled, making an /a/b/g/n station act like an
a/b/g station.  HT40 may be disabled forcing the station to
be HT20 even if the AP and local hardware support HT40.

MAX-AMSDU may be disabled.
AMPDU-Density may be increased.
AMPDU-Factor may be decreased.

This has been successfully tested with ath9k using patched
wpa_supplicant and iw.

v10:
  *  Add check in ieee80211_apply_htcap_overrides to make
     sure we are type NL80211_IFTYPE_STATION.

  *  Memset u.mgd.ht_capa and ht_capa_mask to 0 in
     ieee80211_set_disassoc to make sure we do not try to
     use stale data.

  *  Add cpu_to_le16 when dealing with u.mgd.ht_capa*
     Appears to make no change on x86, but should help
     with certain other platforms.

  *  Addressed other issues brought up in review of v9.

Thanks. I haven't tested it, but see no obvious bugs. :-)

Well, feels like progress!

If you actually want to enable/view the new features, you'll want
to patch hostap and iw.  You could use my trees if you want, though
they have some extra stuff and the ht-caps logic needs the cpu_to_le16
changes and probably a bit of other cleanup at the moment.

https://github.com/greearb/iw-ct

I'll post some clean iw and hostap patches later today if all goes well.

Thanks,
Ben
