Shouldn't advertise and lpa be either "unsigned short" or u16?

No, they don't need to be.



+       lpa = mii->mdio_read(mii->dev, mii->phy_id, MII_LPA);
+
+       /* figure out media and duplex from advertise and LPA values */
+       media = mii_nway_result(lpa & advertise);

^^^^^^^^^^^^^^^^^^^^^^^


        mii_nway_result returns a "unsigned int", so media also doesn't look
good.

mii_nway_result _really_ returns a small bitmapped value, so it doesn't matter.



+ duplex = (media & (ADVERTISE_100FULL | ADVERTISE_10FULL)) ? 1 : 0;


        Or we could do

duplex = (media & ADVERTISE_FULL) ? 1 : 0;


True.  I forgot about that constant...
