From ae54c985cc7daa502da6e7eb3b223a30fbbf4cfb Mon Sep 17 00:00:00 2001 From: Alina Friedrichsen Date: Fri, 23 Jan 2009 05:33:37 +0100 Subject: mac80211: Read the TSF via debugfs This patch adds an low-level driver independent entry to read the TSF value into the debugfs of mac80211. This makes debugging the IBSS handling of wifi drivers easier. Signed-off-by: Alina Friedrichsen Signed-off-by: John W.
