From 4b1a8728eb05c4e5bd26fa3d5a9bbd41224dc2df Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 17 Apr 2023 15:37:51 +0200 Subject: [PATCH 54/70] wifi: mac80211: remove ieee80211_tx_status_8023 It is unused and should not be used. In order to avoid limitations in 4-address mode, the driver should always use ieee80211_tx_status_ext for 802.3 frames with a valid sta pointer.
