nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scan
This commit adds the support to specify the RSSI thresholds per band for each match set. This enhances the current behavior which specifies a single rssi_threshold across all the bands by introducing the rssi_threshold_per_band. These per band rssi thresholds are referred through NL80211_BAND_* (enum nl80211_band) variables as attribute types. Such attributes/values per each band are nested through NL80211_ATTR_SCHED_SCAN_MIN_RSSI. These band specific rssi thresholds shall take precedence over the current rssi_thold per match set. Drivers indicate this support through %NL80211_EXT_FEATURE_SCHED_SCAN_BAND_SPECIFIC_RSSI_THOLD. These per band rssi attributes/values does not specify "default RSSI filter" as done by NL80211_SCHED_SCAN_MATCH_ATTR_RSSI to stay backward compatible. That said, these per band rssi values have to be specified for the corresponding matchset.
