But seems chandef (sta chandef) is a local variable here, not used by the way. So, our chandef is form cfg80211 (sdata->u.ibss.chandef) and we don't change this. Orginaly this sta chandef was used to compare with ibss->chandef.
- if (chandef.center_freq1 != - sdata->u.ibss.chandef.center_freq1) - htcap_ie.cap_info &= - cpu_to_le16(~IEEE80211_HT_CAP_SUP_WIDTH_20_40); But for me this check seems as not needed, eg. We support VHT80 and other ibss have only HT40 support - so we will have different center_freq1 - but still could operate, while sta_add and correct rates for sta configured. One I think we could check here is, if our chandef and sta chandef overlap. Anyway, I am not sure I understand your question correctly, you mean eg. we work in VHT80 mode and other ibss join in VHT160 mode? Does it really matter while we will use sta_add for this new V160 "station" and configure supported rates for this station?
