The problem remains with this firmware:

[root@ct523c-a0af ~]# ethtool -i wlan2
driver: mt7996e
version: 6.7.0-rc3+
firmware-version: ____000000-20231012001354
expansion-rom-version:
bus-info: 0000:0d:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

Do you have a kernel tree that you are using successfully (not an owrt feed of patches)
that you can share?

Thanks,
Ben
