LED trigger for network interfaces.
- Aggregated per-family (lan/wan/wlan).
- Family and flags are taken from device tree properties:
- "family" : simple family string "lan" | "wan" | "wlan"
- "mode" : any combination of "link", "tx", "rx" flags
Priority/combination:
* If "mode" present: flags come from "mode" and take precedence.
Family is taken from "family" if present, otherwise from the LED name.
* If only "family" present: use its family and default flags = link+tx+rx.
* If neither present: fall back to LED device name parsing.
- Suffix "-online" is valid ONLY in the LED name (label),
e.g. "green:wlan-online". It indicates the online variant but is applied
only when DT "mode" is absent.
Behaviour:
- wlan (normal): blink/solid driven by throughput table
- lan/wan (normal): one-shot blink on TX/RX packet change
- *-online variants: steady ON while any interface of the family has carrier
Interfaces are auto-tracked by name match (lan0, wan1, wlan2, phy0, wl1,
ath0, ra0...). Up to MAX_IFACES (16) interfaces per family
This trigger is intended for board/device authors and drivers to provide simple
network-activity LED behaviour without per-interface wiring in userspace.
Refresh bcm27xx patches in the same commit to account for line shifts in
drivers/leds/trigger/Kconfig and Makefile, ensuring clean applies for
bisectability.
