one 6 GHz-only, one 2.4+5+6 GHz) failed with reason 15 whatever the association link, with M3 dropped by mac80211. Non-MLO WPA2-PSK on 5 GHz was fine. With this patch, applied as posted, both MLO SSIDs connect. I tested on v7.3-rc5 and again on v7.3, each plus out-of-tree Glymur platform/board patches; on v7.3 the tri-band SSID connected as MLO (on its 6 GHz link) and rejoined MLO after s2idle resume. That tree also carries your separate dp_peer fix (8b6b871332b5, "Fix failure to create ath12k_dp_peer on MLO reconnect"). I haven't tried the rebase onto ath/main that Jeff asked for.
