From 28a1bcdb57d50f3038a255741ecc83e391e5282e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 4 Oct 2011 18:27:10 +0200 Subject: mac80211: fix offchannel TX cookie matching When I introduced in-kernel off-channel TX I introduced a bug -- the work can't be canceled again because the code clear the skb pointer. Fix this by keeping track separately of whether TX status has already been reported.
