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

[Mariusz]

Mine is from a different supplier - Wallys - and I bought it 2 weeks
ago but not sure how old their stock is. PCB looks slightly different
than Pinapple's. Is it likely to have the same issue?

What I noticed is that not only it does not have board_id preset but
also 6Ghz / 6E is only enabled (at least by the driver) when the
regulatory domain is set to US. Any other setting disables 6Ghz
channels. That is not in line with regulatory situation in EU as lower
6E bands are allowed. Intel AX210 has this right.

Also looking into their pre-compiled driver .ko, they seemed to for
whatever reason customize it. Path is far from standard kernel source
/home/wallystech/qca_ath11k/wt_ath11k/ath11k_5_17_0/

Of course I cannot load their pre-compiled driver due kernel issues. I
used the same kernel 5.17.0 but vermagic was different, I patched
vermagic plus copied symbol_table id from my 5.17.0 kernel ath11k.ko
module to the pre-compiled module which resulted in missing symbols of
course.

Not clear what they did to the driver code and no feedback of course.

Right now the only last clue I am left with is that QCN9074 has 6E on
only when iw reg is set to US. Client on the other hand forces this to
EU via LAR. Lower frequencies match between reg domains i.e. 5955
channel 1 is allowed by both reg domains. Maybe there is something
else at play that client with reg set to EU ignores beacons from AP
with reg set to US. This I cannot overcome for now, client does not
accept any change being intel iwlwifi driver and QCN9074 disables all
6E channels when reg is set to anything else than US.

Mariusz
