I tried this plus the patch it is fixing on 6.2.2+ kernel with 7922 radios,
and behaviour seems worse than before the two patches were applied.

Original problem I was trying to fix is that my STAs will connect fine on 5Ghz,
but then when I try to move them to 2.4Ghz, most will not scan anything.
Packet sniff shows probe responses and requests, so I suspected firmware is
filtering when it should not.

With the two patches applied, even 5Ghz is showing failure, with lots of
beacon loss messages (I am disabling beacon filtering, which previously worked
fine on 7921 nic in 5.19 kernel).

Are there other patches that I should consider to get 7922 to work better in 6.2.2+
kernel?
