Subject: iwlax2xx: no channel=acs_survey and no virtual access points


iwlax2xx-firmware-20221214-145.fc36.noarch
Network controller: Intel Corporation Alder Lake-S PCH CNVi WiFi (rev 11

"channel=acs_survey" don't work at all and times out which maces 5 GHz 
WLAN practically unusable and in a city like vienna with tons of 
networks you really want automatic channel selection

when you don't comment out the last b,ockm for wlan1 you end with "Could 
not set interface wlan1 flags (UP): Device or resource busy Failed to 
add BSS (BSSID=02:ab:cd:ef:12:31)" and hostapd don't start at all

---------------------------

the more than 10 years old "Qualcomm Atheros AR5418 Wireless Network 
Adapter [AR5008E 802.11(a)bgn]" athk9 based card in the old machine just 
worked fine....

so is that the hardware itself, the kernel driver or the firmware?
