Subject: [PATCH net-next 00/12] RollBall / Hilink / Turris 10G copper SFP support


I am resurrecting my attempt to add support for RollBall / Hilink /
Turris 10G copper SFPs modules.

The modules contain Marvell 88X3310 PHY, which can communicate with
the system via sgmii, 2500base-x, 5gbase-r, 10gbase-r or usxgmii mode.

Some of the patches I've taken from Russell King's net-queue [1]
(with some rebasing).

The important change from my previous attempts are:
- I am including the changes needed to phylink and marvell10g driver,
  so that the 88X3310 PHY is configured to use PHY modes supported by
  the host (the PHY defaults to use 10gbase-r only on host's side)
- I have changed the patch that informs phylib about the interfaces
  supported by the host (patch 5 of this series): it now fills in the
  phydev->host_interfaces member only when connecting a PHY that is
  inside a SFP module. This may change in the future.



Marek Behún (7):
  net: phylink: pass supported host PHY interface modes to phylib for
    SFP's PHYs
  net: phy: marvell10g: Use tabs instead of spaces for indentation
  net: phylink: allow attaching phy for SFP modules on 802.3z mode
  net: sfp: Add and use macros for SFP quirks definitions
  net: sfp: create/destroy I2C mdiobus before PHY probe/after PHY
  net: phy: mdio-i2c: support I2C MDIO protocol for RollBall SFP modules
  net: sfp: add support for multigig RollBall transceivers

Russell King (3):
  net: sfp: augment SFP parsing with phy_interface_t bitmap
  net: phylink: use phy_interface_t bitmaps for optical modules
  net: phy: marvell10g: select host interface configuration

Russell King (Oracle) (2):
  net: phylink: add ability to validate a set of interface modes
  net: phylink: rename phylink_sfp_config()
