From 6f48422a29714ed92f6136d9e7d3ff39c75607d7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 25 Feb 2008 16:27:44 +0100 Subject: [PATCH] mac80211: remove STA infos last_ack stuff These things aren't used and the only possible use is within rate control algorithms, however those can, if they need it, keep track of it in their private data. last_ack_ms isn't even updated so completely useless.
