‘/sys/kernel/debug/ieee80211’: No such file or directory

Hello, I came up with the same error as the title, but in my case the modprobe of both mac80211 and mac80211_hwsim works. This is the error that i get:

mn --wifi --mac --arp --ap p4ap --client-isolation
*** Adding stations:

Warning! Error when loading mac80211_hwsim. Please run sudo 'mn -c' before running your code.
Further information available at /tmp/mn-wifi-mac80211_hwsim.log.

Any suggestions? I use ubuntu 18.04 with kernel version 5.15.0-46-generic.

This seems that you don't have all the mac80211 stack in your kernel. I have never seen this before.
