For MLO cases, this leaves the additional links without proper WMM defaults if hostapd does not supply per-link WMM parameters, leading to inconsistent QoS behavior across links. Set default WMM parameters for each link during ieee80211_vif_update_links(), because this ensures all individual links in an MLD have valid WMM settings during bring-up and behave consistently across different BSS.
