Re: [PATCH v4] wifi: mac80211: fix monitor mode frame capture for real chanctx drivers

Hi, after my yesterday's email with the tests results. As you can see,
all the cases are working but the 5ghz+VIF+DoS. Will this patch be
added anyway while looking for a fix for this specific case? if so,
from what kernel version will it be available? 7.0 I guess, just to
confirm and update airgeddon wiki-docs.
Thanks and Regards.
