Subject: [PATCH v4 06/14] mac80211: reduce duplication in tx status functions
Date: Tue, 8 Sep 2020 14:36:54 +0200 [thread overview]
Message-ID: <20200908123702.88454-7-nbd@nbd.name> (raw)
In-Reply-To: <20200908123702.88454-1-nbd@nbd.name>
Move redundant functionality from __ieee80211_tx_status into
ieee80211_tx_status_ext. Preparation for unifying with the 802.3 tx status
codepath.
