From ef8f66cd1d6f360340a73ee7ed0492ff0f5f42ea Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sun, 17 Feb 2008 17:33:57 +0100 Subject: [PATCH] rt2x00: Remove reset_tsf() Specifications indicate the TSF registers are read-only, so there is no point in writing 0 to those registers. As far as I know there isn't another way to reset the TSF registers. So removing these callbacks will notify mac80211 about the lack of support. Signed-off-by: Ivo van Doorn Signed-off-by: John W.
