What happened?

I have been testing both an Intel BE200 and a Mediatek MT7925 (each in m.2 card form factor, STA mode) with a TP-Link BE3600 dual band AP. BTW, if anyone wants any specific A/B testing between these two cards, let me know.

With the BE200, I get the MLO lines at the bottom of the output of iw dev. With the MT7925, no MLO output lines. See iw dev output above. I have forced the STA to associate with each of the AP's BSSIDs to make sure it really is trying to connect to the MLO activated SSID, but no change.

ethtool -i wlan0
driver: mt7925e
version: 6.12.1-arch1-1
firmware-version: ____000000-20241104133053
expansion-rom-version:
bus-info: 0000:aa:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

This is really not a big deal for me as I can go back to the BE200 (both are giving pretty similar real world iperf3 results throughout my house). Even the BE200 seems to be only using enhanced multi-link single radio (EMSLR) anyway, so no boost in real throughput or latency with the BE200. But I like Mediatek better in general, so if anyone has any tricks to get MLO working on MT7925, please let me know. Or if the answer is just a "wait for it to make it into the firmware", that's fine too.
