In 6 GHz, QoS/EDCA operation is mandatory as per IEEE 802.11ax/802.11be. APs are not required to include a WMM Information or WMM Parameter element in Beacon or Probe Response frames, unlike in 2.4/5 GHz. Instead, stations must assume that QoS is always enabled and use EDCA (default EDCA parameters apply if no explicit EDCA Parameter Set is present). Currently, mac80211 only sets bss->wmm_used when a WMM IE is present. When it is missing in 6 GHz, mac80211 wrongly downgrades the connection to legacy rates, resulting in unsuccessful authentication and association. Users see log messages like "WMM/QoS not supported, limiting to legacy" "Rejecting non-HE 6/7 GHz connection" Fix this by unconditionally setting bss->wmm_used = true for 6 GHz BSSs during scan result processing. This ensures that mac80211 maintains HE/EHT capabilities even when the WMM IE is absent.
