Subject: [PATCH 1/2] wifi: mac80211: reload info pointer in ieee80211_tx_dequeue()
Date: Wed, 31 Jan 2024 16:49:10 +0100 [thread overview]
Message-ID: <20240131164910.b54c28d583bc.I29450cec84ea6773cff5d9c16ff92b836c331471@changeid> (raw)
From: Johannes Berg <johannes.berg@intel.com>
This pointer can change here since the SKB can change, so we
actually later open-coded IEEE80211_SKB_CB() again. Reload
the pointer where needed, so the monitor-mode case using it
gets fixed, and then use info-> later as well.
