Upon establishing a 2.5GBASET link, the PHY will reconfigure it's MII interface to 2500BASEX. At 5G, the PHY will reconfigure it's interface to 5GBASE-R, but this mode isn't supported by any MAC for now. This was tested with : - The 88X3310, which is on the MacchiatoBin - The 88E2010, an Alaska PHY that has no fiber interfaces, and is limited to 5G maximum speed.
