Could you expand that.

Does it mean the hardware will look at the results of the autoneg and disable/enable LPI depending on those results?

Yes.

I also assume this means it is not possible to force LPI on/off, independent of autoneg?

Correct. set_eee call in this driver is filtering (tx_lpi == false) to reflect HW functionality.
