sundance: Really read addr 0
Make phy 0 actually be read, as it is not being right now as we have: int mii_status = mdio_read(dev, phy, MII_BMSR); int phyx = phy & 0x1f; When we should have instead: int phyx = phy & 0x1f; int mii_status = mdio_read(dev, phyx, MII_BMSR); so that when phy, in the end of the (phy = 1; phy <= 32...) loop gets to 32 phyx gets to 0, i.e. we were reading at 32, when the intended read was for 0.
