Would have been nice to have some info about the relevant components directly 
in the subject. And iw is not that relevant - it is just a tool which you used 
to inspect the state of the system. I have therefore adjusted the subject 
slightly

This is not part of the driver. But the kernel might use it - like in your 
example. Unfortunately, the previously mentioned firmware includes an own 
regulatory db which is then used for the phy0 ("self managed").

But the commit at least provides some good reasons why Intel might consider 
enabling the indoor channel in the frequency range 5945 - 6425 MHz.  It would 
therefore be nice to know whether/when Intel actually has plans to enable 
these channels in Germany (and not only for the US) in the near future. Maybe 
there are even newer (test) firmware versions available but I am not aware 
of any newer firmware version than the previously mentioned one [1].
And this firmware was published for linux-firmware right around the time when
Vfg. 55/2021 was released - so it is to some extend expected that Intel didn't 
yet incorporated such a change.

I only saw newer releases for other HW [2] but not for Ty.

Kind regards,
	Sven

Seems like there was just a newer release with Sharadanand should test

Kind regards,

It looks like 6GHz channels are still disabled in DE with this firmware 
version.

Kind regards,

Johannes asked to forward it to the support system [1]. This was done now by 
Sharadanand [2]. Interested persons might check the status there in case there 
is no update in this thread.

Just for the laughs: Intel recommended [3] a couple of weeks ago to get a 
cellar [4] where your Intel card can only receive an (from a legal perspective 
incorrectly configured) AP which was set to the US country code. While it is 
dubious for various reasons, this was part of the marked as solution (which 
closed the discussion). I still hope that Intel customers aren't forced to 
move their apartments into properly shielded cellars to use Intel HW. Would 
give the German term "Kellerkind" a new meaning. :)

Kind regards,
	Sven

[4] I still have some hope that they actually meant "shield box" here. And only 
    recommended it for controlled tests and not normal operation

The new firmware [3] seems to solve this. I have posted some output in the 
intel community thread [4].

Kind regards,
