I tried this against an AP that supports 160 MHz windows and shows
other devices using them, but my notebook does not start doing so:

iwx0 at pci0 dev 20 function 3 "Intel Wi-Fi 6 AX211" rev 0x01, msix
iwx0: hw rev 0x370, fw 77.f92b5fed.0, pnvm 285b3568, address a0:29:42:f6:8f:1a

That is, 'ifconfig wlan' keeps showing 'chan 60' and 'ifconfig wlan can'
lacks channel 163, which it should, if I understand this table correctly:
