From 9d139c810a2aa17365cc548d0cd2a189d8433c65 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 9 Jul 2008 14:40:37 +0200 Subject: mac80211: revamp beacon configuration This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well. Signed-off-by: Johannes Berg Signed-off-by: John W.
