From d0472ccb4f116ab98c969a4db411aa9007fd1f9d Mon Sep 17 00:00:00 2001 From: Ramanathan Choodamani Date: Thu, 5 Feb 2026 15:12:16 +0530 Subject: wifi: mac80211: set default WMM parameters on all links [ Upstream commit 2259d14499d16b115ef8d5d2ddc867e2be7cb5b5 ] Currently, mac80211 only initializes default WMM parameters on the deflink during do_open(). 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.
