Subject: [PATCH net-next v2 0/2] net: phy: disable EEE on TI PHYs

Hi,

Towards the end of October, we discussed EEE on TI PHYs which seems to
cause problems with the stmmac hardware. This problem was never fully
diagnosed, but it was identified that TI PHYs do not support LPI
signalling, but report that EEE is supported, and they implement the
advertisement registers and that functionality.

This series allows PHY drivers to disable EEE support.

v2:
- integrate Oleksij Rempel's review comments, and merge update
  into patch 2 to allow EEE on non-1G variants.
