I think this is the source of confusion with linux/phy.h and
linux/phy/phy.h.

What would PHY_INTERFACE_MODE_2500SGMII use?

Where is this all getting confused? Should the caller to
mvpp22_comphy_init() actually be passing PHY_INTERFACE_MODE_2500SGMII?
What is the MAC actually doing at this point? 2500BASEX or 2500SGMII?

At minimum there needs to be a comment that this is not a typ0,
otherwise you are going to get patches submitted to 'fix' this.

	Thanks
