Subject: mac80211: fix ethtool stats for non-station interfaces
From: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
commit e13bae4f807401729b3f27c7e882a96b8b292809 upstream.
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.
