I have a system with Intel AX201 not using 2 spatial streams in the RX

similar behavior with an AX200 system. I'm seeing the same behavior on
5.15.12 as I am with 5.16.0-rc8 so I didn't mark it as a regression.
Windows works as expected.
I have opened bug 215465[0] with some more detail.

We saw something similar with ax210, but only on 6E, in kernel 5.15.7+.
On 5Ghz, it worked 2x2 as expected.
On a 5.15.0-rc something, it worked OK for us.
We verified same firmware is used in both cases, but have not fully
bisected the problem yet but we are
working on it. In case you find the problem patch before us, please let
me know!
Thanks,

I'm still seeing this as far back as 5.11.12, so I'm not convinced this
is a regression. At least for the 5 GHz / 802.11ac case.
