Weird thing... I set the AP to 20MHz:

wdev 0x10000000b

ssid HolyLan

Then I reset the client and tried again and it still wants to use channel
153:

After a couple of dozens of retries the correct channel / frequency was
finally selected and connection was successfully established.
That's something for Adrian having worked on that driver.
But it looks like the connection is 'a', not 'ac' that I expected?
Yes given you showed in the list channels yourself that there was no VHT
given regdomain.xml for NONE/UA does not know about that.
UA is close but not exactly matching the current ETSI regdomain
definition (careful, you are not allowed as many mW in some case, etc.) from
what I can see in what linux wireless-regd has.
