From 095dfdb0c479661f437b24b85e31f0d0b841eab6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 26 May 2010 17:19:25 +0200 Subject: [PATCH] mac80211: remove tx status ampdu_ack_map There's a single use of this struct member, but as it is write-only it clearly not necessary. Thus we can free up some space here, even if we don't need it right now it seems pointless to carry around the variable. Signed-off-by: Johannes Berg Signed-off-by: John W.
