Flags to indicate what changed
enum ieee80211_rate_control_changed { IEEE80211_RC_BW_CHANGED, IEEE80211_RC_SMPS_CHANGED, IEEE80211_RC_SUPP_RATES_CHANGED, IEEE80211_RC_NSS_CHANGED };
IEEE80211_RC_BW_CHANGED
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.
IEEE80211_RC_SMPS_CHANGED
The SMPS state of the station changed.
IEEE80211_RC_SUPP_RATES_CHANGED
The supported rate set of this peer changed (in IBSS mode) due to discovering more information about the peer.
IEEE80211_RC_NSS_CHANGED
N_SS (number of spatial streams) was changed by the peer
