+Subject: [PATCH] mac80211: make LED trigger names available early
+
+The throughput trigger will require doing LED
+classdev/trigger handling before register_hw(),
+so drivers should have access to the trigger
+names before it. If trigger registration fails,
+this will still make the trigger name available,
+but that's not a big problem since the default
+trigger will the simply not be found.

+Subject: mac80211: add throughput based LED blink trigger
+From: Johannes Berg <johannes.berg@intel.com>
+
+iwlwifi and other drivers like to blink their LED
+based on throughput. Implement this generically in
+mac80211, based on a throughput table the driver
+specifies. That way, drivers can set the blink
+frequencies depending on their desired behaviour
+and max throughput.
+
+All the drivers need to do is provide an LED class
+device, best with blink hardware offload.
