From 8cab7581dba90b0519e25784e08feb5dedde737f Mon Sep 17 00:00:00 2001 From: Alina Friedrichsen Date: Fri, 23 Jan 2009 05:39:13 +0100 Subject: ath5k: Read and write the TSF via debugfs This patch updates the ath5k specific entry in the debugfs to read and reset the TSF value, to allowing write it, too. This makes debugging the IBSS handling of wifi drivers _much_ easier. Signed-off-by: Alina Friedrichsen Signed-off-by: John W.
