So what happens when i do:

ethtool --set-eee eth42 off

or

ethtool --set-eee eth42 tx-lpi on

I don't now what phylib does with advertise in these cases, but maybe
you need to go behind phylink/phylib back and set advertise to 0, so
that the MAC does the right thing?

Or you need to return -EOPNOTSUPP for these?
