-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.
-
-Signed-off-by: Johannes Berg <johannes.berg@intel.com>
----
-v2: turn off LED when turning off radio
-v3: - use only data frames
- - fix update frequency to 1 second
- - use DIV_ROUND_UP
