mt7921au: Client Mode WDS/4addr not working

[ntzb]

Hi, to not mix the AP mode issue at https://github.com/morrownr/USB-WiFi/issues/392 I'm starting a new issue. I tried to activate 4addr on regular client mode, but it refused working. my device is FU-AX1800, with latest firmware, and chip mt7921au.

what I tried:

1. multiple OS (debian, arch, clear linux) on a celeron mini pc.
2. take down the interface before doing any changes ip link set dev wlx90de80d6883f down
3. setting 4addr on the interface itself: iw dev wlx90de80d6883f set 4addr on
4. setting 4addr on a new pseudo interface: iw dev wlx90de80d6883f interface add myNewIface type managed 4addr on

in all cases I got: command failed: Operation not supported (-95)

@morrownr since you successfully got it to work, can you please share your full env and steps taken?

@morrownr any help will be appreciated

I'm watching but my inability to dig deeper into this issue is due to some health issues in my family so my time is llimited. Hopefully, at some point, I have more time. There are some pretty smart people that stop by here not necessarily on a daily basis as this is not a social media site but over time some help should come along.

of course, sorry. all the best

decided to give it another go with OpenWRT, same thing (Operation not supported):

daemon.notice hostapd: Set new config for phy phy0:

daemon.err wpa_supplicant[1635]: Could not read interface phy0-sta0 flags: No such device
daemon.err wpa_supplicant[1635]: phy0-sta0: Failed to initialize driver interface

can the x86 hardware itself block the ability to use 4addr? all of my tries were done on the same PC
