Wallys DR9074-6E(PN02.7) QCN9074 refuses to work on 6GHz band

[Mariusz]

Hi,

As support for QCN9074 got better I went ahead and built a 6E linux
based AP. Dell R720 server x86 running Linux s4 5.19.0-23-generic
#24-Ubuntu SMP PREEMPT_DYNAMIC Fri Oct 14 15:39:57 UTC 2022 x86_64
x86_64 x86_64 GNU/Linux.

My issue is that I cannot get it working on 6GHz bands but it works
fine on 5GHz. I bought 6E version  and since this is a single band
module it cannot be both 5G & 6G and linux driver does not agree with
it being 6E version:

I am using the latest firmware files from ath11k tree. Is there any
special firmware to force this to 6GHz? I read somewhere board_id
determines which one it is and 255 disables 6GHz but I miss more data
on that.

It works fine in 5GHz but this is not what I purchased it for, so I am
puzzled if this is something in software or I was sold wrong
hardware.Is there a specific board-2.bin for 6GHz? Since the 9074 chip
is the same in all versions perhaps this is a software hiccup.

Any clues are welcome.
