mac80211: fix ethtool stats for non-station interfaces
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. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
