mac80211: make LED triggering depend on activation 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>

mac80211: add throughput based LED blink trigger 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.

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.
