When LED triggers are compiled in, but not used, mac80211 will still call them to update the status. This isn't really a problem for the assoc and radio ones, but the TX/RX (and to a certain extend TPT) ones can be called very frequently (for every packet.) In order to avoid that when they're not used, track their activation and call the corresponding trigger (and in the TPT case, account for throughput) only when the trigger is actually used by an LED. Additionally, make those trigger functions inlines since theyre only used once in the remaining code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
