From: Johannes Berg <johannes.berg@intel.com>
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.
