From cdcb006fbe7a74b5f7827f5c5c27e11399a2fab7 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Mon, 7 Jan 2008 19:45:24 +0100 Subject: mac80211: Add radio led trigger Some devices have a seperate LED which indicates if the radio is enabled or not. This adds a LED trigger to mac80211 where drivers can hook into when they are interested in radio status changes. v2: Check hw.conf.radio_enabled when calling start().
