I don't know of any PHY driver you can follow, those that do have a
temperature sensor just report the temperature and don't do anything
in addition.

You might need to look at thermal zones, and indicate there has been a
thermal trip point. That could then be used by the thermal subsystem
to increase cooling via a fan, etc. In theory, you could also make the
PHY active to thermal pressure, by forcing the link to renegotiate to
a lower link speed. If you decide to go this route, please try to make
is generic to any PHY. But its going to be quite a disruptive thing,
the link will be lost of a little over a second...
