Subject: [PATCH 1/3] mac80211: clean up get_tx_stats callback
Date: Tue, 29 Apr 2008 17:18:59 +0200 [thread overview]
Message-ID: <20080429152040.485831000@sipsolutions.net> (raw)
In-Reply-To: 20080429151858.253229000@sipsolutions.net
The callback takes a ieee80211_tx_queue_stats with a contained
array of ieee80211_tx_queue_stats_data, remove the former, rename
the latter to ieee80211_tx_queue_stats and make tx_stats() take
the array directly.
