We might want to rethink this. PHYs typically have 2 or 3 LEDs. So we
want a way to indicate which LED of a PHY it is. So i suspect we will
want something like
ethphyN-led0, ethphyN-led1, ethphyN-led2.
I would also suggest N starts at 42, in order to make it clear it is a
made up arbitrary number, it has no meaning other than it is
unique. What we don't want is people thinking ethphy0-led0 has
anything to do with eth0.

I do think it is clear that the base name is mostly irrelevant and not
going to be used in any meaningful way. You are unlikely to access
these LEDs via /sys/class/leds. You are going to go into
/sys/class/net/<ifname> and then either follow the device symlink, or
the phydev symlink and look for LEDs there. And then only the -ledM
part of the name might be useful. Since the name is mostly
meaningless, we should just decide and move on.
