From 2cc6f5a715cf9f7d5ca8fd2bde62130fcfd90b94 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 19 Oct 2016 15:02:32 +0200 Subject: mac80211: set wifi_acked[_valid] bits for transmitted SKBs 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.
