leds: trigger: netdev: Add support for tx_err and rx_err notification with LEDs
This patch provides support for enabling blinking of LEDs when RX or TX
errors are detected.
Approach taken in this patch is similar to one for TX or RX data
transmission indication (i.e. TRIGGER_NETDEV_TX/RX attribute).
One can inspect transmission errors with:
ip -s link show eth0
Example LED configuration:
cd /sys/devices/platform/amba_pl@0/a001a000.leds/leds/
echo netdev > mode:blue/trigger && \
echo eth0 > mode:blue/device_name && \
echo 1 > mode:blue/tx_err
