Hi!

The WAN port of the 370-RD has a Marvell PHY, with one LED on
the front panel. List this LED in the device tree.

/sys/class/leds/WAN is not acceptable.

As i said here, that is not what it gets called:

It can be found in /sys/class/leds/f1072004.mdio-mii:00:WAN. But when
we come to using it for ledtrig-netdev, the user is more likely to follow
/sys/class/net/eth0/phydev/leds/f1072004.mdio-mii\:00\:WAN/

Is that acceptable?

What are the acceptance criteria?

Acceptance criteria would be "consistent with documentation and with
other similar users". If the LED is really white, it should be
f1072004.mdio-mii\:white\:WAN, but you probably want
f1072004.mdio-mii\:white\:LAN (or :activity), as discussed elsewhere in the thread.

Documentation is in Documentation/leds/well-known-leds.txt , so you
should probably add a new section about networking, and explain naming
scheme for network activity LEDs. When next users appear, I'll point
them to the documentation.

Does that sound ok?
