ax210: Why no 6E channels valid in regdom?

ax210: Why no 6E channels valid in regdom?

[Ben Greear]

I cannot figure out why my ax210 won't show any 6E channels.  It worked for a bit a few days
ago, but now it does not..and not sure why.  Looks like it uses some internal regdom.

Any idea from these logs what is going on?

Is that 'mcc' logic actually able to read the cellular network?  I am near enough to Canada
that sometimes my mobile phone will pick up those towers...could the ax210 possibly be
hearing the same and forcing itself to OO regdom, which would cause it to disable all 6E
channels?

Thanks,

Ok, I think I see the pattern now.

You have to admin-up the station and start scanning before it will show the
6E channels in 'iw reg get'.  And that makes the 'band 4' frequencies become
usable as well, as seen in 'iw phy foo info'.

So, a bit confusing for me, but I guess it works as intended.

This is with 5.11-rc5+ kernel and latest ax210 FW that I can find.
