I tried to set up hostapd to do HT40-, but for whatever reason,

Is it really *reqired* that wmm_param exist to enable HT mode?
From mlme.c:
if (elems.ht_info_elem&& elems.wmm_param&&
(sdata->local->hw.queues>= 4)&&
!(ifmgd->flags& IEEE80211_STA_DISABLE_11N))
changed |= ieee80211_enable_ht(sdata, elems.ht_info_elem,
cbss->bssid, ap_ht_cap_flags);
802.11n-2009 says it is required.
Do you know the pertinent section, or some keywords to search for? I'm
unable to find anything useful.
No, I got confused. 802.11n says an HT STA is a QoS STA (5.2.9), but in
practice WMM is tested/certified instead of QoS.
So maybe we can remove that check for wmm_param, but put in a printk
to warn users that their AP is probably mis-configured?
Thanks,
