[PATCH 01/14] mac80211: pass station to ieee80211_vht_cap_ie_to_sta_vht_cap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

Like with HT, make things a bit simpler in future patches by
passing the station to ieee80211_vht_cap_ie_to_sta_vht_cap()
instead of the vht_cap pointer. Also disable VHT here if HT
isn't supported.
