Dear Baochen Qiang, All,
Thanks for your responses! I travelled the past couple of days, thus could only test today.
Your input is much appreciated, as I could make it work as you suggested.
Should I see EMLSR support?
I noticed that “iw” output no longer has a TX nor RX Rate:

How should I determine MCS when this output is missing?

I have no WLAN M.2 Slot on this board, thus I’m using a PCIe X4 to M-Key card and then an adapter to convert M-Key to A/E-Key (which unfortunately only appears to support x1 instead of x2).
USB is broken out and attached to USB-Pins on the mainboard. I know this may not be optimal, but it works.

I can confirm that the issue is NOT seen in ath-current-20250608
$ git clone --depth 1 --branch ath-current-20250608 git://git.kernel.org/pub/scm/linux/kernel/git/ath/ath.git
I applied https://0x0.st/8g7F.diff against ath-current-20250608 and MLO works fine, including 6 GHz.
