Subject: [PATCH] mac80211: set wifi_acked[_valid] bits for transmitted SKBs
Date: Wed, 11 Jan 2017 16:42:10 +0100 [thread overview]
Message-ID: <20170111154210.1488-1-johannes@sipsolutions.net> (raw)
From: Johannes Berg <johannes.berg@intel.com>
There may be situations in which the in-kernel originator of an
SKB cares about its wifi transmission status. To have that, set
the wifi_acked[_valid] bits before freeing/orphaning the SKB if
the destructor is set. The originator can then use it in there.
