When the indicator is set to monitor Ethernet, it can work on either
LAN1, LAN2 or both LAN interfaces.

On NUC leds, this is already offloaded to HW/firmware.
All it takes is to tell the BIOS via ACPI/WMI what LED will be used
for monitoring the Ethernet activity, and on what port(s).

HDD activity is also HW/firmware monitored. The only thing the Kernel
needs to to is to select what LED will be set as the HDD activity
indicator.
Thanks,
