From e13bae4f807401729b3f27c7e882a96b8b292809 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 8 Jul 2013 10:43:31 +0200 Subject: [PATCH] mac80211: fix ethtool stats for non-station interfaces As reported in https://bugzilla.kernel.org/show_bug.cgi?id=60514, the station loop never initialises 'sinfo' and therefore adds up a stack values, leaking stack information (the number of times it adds values is easily obtained another way.) Fix this by initialising the sinfo for each station to add.
