From f850e00fcd7767d01101e2f0a6d464bee8e48b47 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Jul 2011 19:50:53 +0200 Subject: [PATCH] mac80211: let key iteration get keys in install order ieee80211_iter_keys() currently returns keys in the backward order they were installed in, which is a bit confusing. Add them to the tail of the key list to make sure iterations go in the same order that keys were originally installed in. Signed-off-by: Johannes Berg Signed-off-by: John W.
