From 42b941cd6738d26abdae2f3fee520b79ea77e2fe Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 11 Dec 2023 09:05:23 +0200 Subject: wifi: mac80211: add a flag to disallow puncturing There may be cases where puncturing isn't possible, and a connection needs to be downgraded. Add a hardware flag to support this. This is likely temporary: it seems we will need to move puncturing to the chandef/channel context.
