Subject: [PATCH net-next 0/3] net: phy: marvell10g: implement suspend/resume callbacks

Hello,

This series implements the suspend/resume callbacks in the marvell10g
PHY driver:

- When the PHY isn't used, it is set in low power mode.
- At boot time we might now know the PHY status (as it's depending on
  the hardware configuration, or on what the previous stages
  configured), it is forced in low power.

Doing this prevents a PHY which was initialized in a previous stage from
negotiating with the link partner when a local port is down. If the PHY
isn't shutdown when a port is not used, the link partner's PHY may
report the link being up while it's not.

Thanks,
Antoine
