RollBall 10G SFP modules, which this series prepares support for, contain 88X3310 PHY and thus can work in USXGMII. By defualt they use MACTYPE=6 (10gbase-r with rate matching), but when this series and the series that adds support for RollBall SFPs are merged, then the SFP module will work in USXGMII if USXGMII is supported by the host MAC.
