Specifically, the commit df78a0c0b67d ("nl80211: S1G band and channel definitions") introduced the NL80211_BAND_S1GHZ attribute to nl80211_band, but it neglected to update the nl80211_match_band_rssi_policy accordingly. Similar commits that add new band types, such as the initial commit 1e1b11b6a111 ("nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scan"), the commit e548a1c36b11 ("cfg80211: add 6GHz in code handling array with NUM_NL80211_BANDS entries"), and the commit 63fa04266629 ("nl80211: Add LC placeholder band definition to nl80211_band"), all require updates to the policy. Failure to do so could result in accessing an attribute of unexpected length in the function nl80211_parse_sched_scan_per_band_rssi. To resolve this issue, this commit adds the policy for the NL80211_BAND_S1GHZ attribute.
