NAME
       enum_ieee80211_rate_control_changed - flags to indicate what changed

SYNOPSIS
       enum ieee80211_rate_control_changed {
	 IEEE80211_RC_BW_CHANGED,
	 IEEE80211_RC_SMPS_CHANGED,
	 IEEE80211_RC_SUPP_RATES_CHANGED,
	 IEEE80211_RC_NSS_CHANGED
       };

CONSTANTS
       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
