From d5e01266e7f5fa12400d4c8aa4e86fe89dcc61e9 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 19 Jun 2023 22:46:58 +0200 Subject: leds: trigger: netdev: add additional specific link speed mode Add additional modes for specific link speed. Use ethtool APIs to get the current link speed and enable the LED accordingly. Under netdev event handler the rtnl lock is already held and is not needed to be set to access ethtool APIs. This is especially useful for PHY and Switch that supports LEDs hw control for specific link speed. (example scenario a PHY that have 2 LED connected one green and one orange where the green is turned on with 1000mbps speed and orange is turned on with 10mpbs speed) On mode set from sysfs we check if we have enabled split link speed mode and reject enabling generic link mode to prevent wrong and redundant configuration. Rework logic on the set baseline state to support these new modes to select if we need to turn on or off the LED. Add additional modes: - link_10: Turn on LED when link speed is 10mbps - link_100: Turn on LED when link speed is 100mbps - link_1000: Turn on LED when link speed is 1000mbps Signed-off-by: Christian Marangi Reviewed-by: Andrew Lunn Acked-by: Lee Jones Signed-off-by: Jakub Kicinski --- include/linux/leds.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/linux/leds.h') diff --git a/include/linux/leds.h b/include/linux/leds.h index 8af62ff431f0..126b79019429 100644 --- a/include/linux/leds.h +++ b/include/linux/leds.h @@ -555,6 +555,9 @@ static inline void *led_get_trigger_data(struct led_classdev *led_cdev) /* Trigger specific enum */ enum led_trigger_netdev_modes { TRIGGER_NETDEV_LINK = 0, + TRIGGER_NETDEV_LINK_10, + TRIGGER_NETDEV_LINK_100, + TRIGGER_NETDEV_LINK_1000, TRIGGER_NETDEV_TX, TRIGGER_NETDEV_RX, -- cgit v1.2.3
