Hi Pavel

What i ended up with is:

f1072004.mdio-mii:00:white:wan

The label on the box is WAN, since it is meant to be a WiFi routers,
and this port should connected to your WAN. And this is what the LED
code came up with, given my DT description for this device.

I added a patch with the following text:

* Ethernet LEDs

Currently two types of Network LEDs are support, those controlled by
the PHY and those by the MAC. In theory both can be present at the
same time for one Linux netdev, hence the names need to differ between
MAC and PHY.

Do not use the netdev name, such as eth0, enp1s0. These are not stable
and are not unique. They also don't differentiate between MAC and PHY.

** MAC LEDs

Good: f1070000.ethernet:white:WAN
Good: mdio_mux-0.1:00:green:left
Good: 0000:02:00.0:yellow:top

The first part must uniquely name the MAC controller. Then follows the
colour.  WAN/LAN should be used for a single LED. If there are
multiple LEDs, use left/right, or top/bottom to indicate their
position on the RJ45 socket.

** PHY LEDs

Good: f1072004.mdio-mii:00: white:WAN
Good: !mdio-mux!mdio@2!switch@0!mdio:01:green:right
Good: r8169-0-200:00:yellow:bottom

The first part must uniquely name the PHY. This often means uniquely
identifying the MDIO bus controller, and the address on the bus.
