Some internet providers are already starting to offer 2.5G copper connectivity to their users. On Turris Omnia the SFP port is capable of 2.5G speed, so we tested some copper SFP modules. This adds support to the SFP subsystem for 10G RollBall copper modules which contain a Marvell 88X3310 PHY. By default these modules are configured in 10GKR only mode on the host interface, and also contain some bad information in EEPROM (the extended_cc byte). The PHY in these modules is also accessed via a different I2C protocol than the standard one. Patch 1 adds support for this different I2C MDIO bus. Patch 2 adds support for these modules into the SFP driver. Patch 3 changes phylink code so that a PHY can be attached even though 802.3z mode is requested.
