From 7643a2c3fcc13cd6fbd731f214463547383418ae Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 2 Jun 2009 13:01:39 +0200 Subject: cfg80211: move txpower wext from mac80211 This patch introduces new cfg80211 API to set the TX power via cfg80211, puts the wext code into cfg80211 and updates mac80211 to use all that. The -ENETDOWN bits are a hack but will go away soon. Signed-off-by: Johannes Berg Signed-off-by: John W.
