Subject: wpa_supplicant can't scan channels 12-13 on RPi 4

I=E2=80=99m running wpa_supplicant on Alpine Linux 3.15 aarch64 on RPi 4 =
and it can only scan channels up to 11 in 2.4 GHz range. I deliberately =
setup a wifi that runs on channel 12 to see, if it will find it and it =
won=E2=80=99t.

If I run an identical scan on Raspberry Pi OS on the same RPi, it finds =
it, both on channels 12 and 13. In both cases I set the country to CZ =
and rebooted the device.

It looks like there must be some difference somewhere in Alpine, that =
causes it to ignore channels 12 and 13.

If I can get some ideas about what I=E2=80=99m doing wrong, I=E2=80=99ll =
appreciate it. Thank you!
