This configuration will be useful for the application like steering which requires change in the station's current signal strength. New NL80211_CMD_STA_MON introduced to configure the RSSI threshold using NL80211_ATTR_CQM nested attributes. The MAC address of a station is passed in NL80211_ATTR_MAC. And NL80211_ATTR_STA_MON_FIXED_THOLD introduced to have this RSSI threshold as a fixed(not modifying the low and high threshold upon crossing the threshold) or moving(modifying low and high threshold upon crossing the threshold) thresholds. Depends on the application's use case user can have either fixed or moving RSSI range thresholds. cfg80211_sta_mon_rssi_notify introduced to notify change in the station's signal stregnth cross event using NL80211_CMD_NOTIFY_STA_MON. Driver supporting this feature should advertise NL80211_EXT_FEATURE_STA_MON_RSSI_CONFIG feature flag.
