From 196ac1c13d4db6c276dbb1c9190c8d7d45a83f1f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 5 Jun 2012 14:28:40 +0200 Subject: mac80211: do remain-on-channel while idle The IDLE handling in HW off-channel is broken right now since we turn off IDLE only when the off-channel period already started. Therefore, all drivers that use it today (only iwlwifi!) must support off-channel while idle, so playing with idle isn't needed at all. Off-channel in general, since it's no longer used for authentication/association, shouldn't affect PS, so also remove that logic. Also document a small caveat for reporting TX status from off-channel frames in HW remain-on-channel. Signed-off-by: Johannes Berg Signed-off-by: John W.
