}; The bandwidth that can be used to transmit to this station changed. The actual bandwidth is in the station information -- for HT20/40 the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag changes, for HT and VHT the bandwidth field changes.
The SMPS state of the station changed.
The supported rate set of this peer changed (in IBSS mode) due to discovering more information about the peer.
N_SS (number of spatial streams) was changed by the peer
