Subject: [PATCH wireless 1/8] wifi: mac80211: fix idle calculation with multi-link
Date: Thu, 18 Apr 2024 10:52:19 +0200 [thread overview]
Message-ID: <20240418105220.90df97557702.I05d2228ce85c203b9f2d6da8538cc16dce46752a@changeid> (raw)
From: Johannes Berg <johannes.berg@intel.com>
The vif's idle state doesn't automatically go to true when
any link removes the channel context, it's only idle when
_all_ links no longer have a channel context. Fix that.
