From fd5b74dcb88cfc109d6576b22deaef6f47f82c12 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 19 Dec 2007 02:03:36 +0100 Subject: cfg80211/nl80211: implement station attribute retrieval After a station is added to the kernel's structures, userspace has to be able to retrieve statistics about that station, especially whether the station was idle and how much bytes were transferred to and from it. This adds the necessary code to nl80211. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S.
